MythTV 0.17 Released
foobar01 writes "MythTV 0.17 has been released. Changes include Mac OS X frontend support, big improvements to DVB and HDTV support, "timestretch" feature (for changing playback speed but not the pitch so you can watch shows more quickly), firewire capture support for cable boxes with firewire output, and widescreen user interface support. See the changelog for the full list of changes."
Obviously this relates because of the native Apple Frontend, but is there any other reason this is in the apple section of slashdot? This project is still primarily a linux toy, is it not? (real question).
Who's ready for a Mac Mini frontend?

That means I can watch 24 in 18.
I agree, frontend support for the mac was one of the bigger changes, but... it still will not record tv shows on a mac. it can only be used to watch already-recorded shows. Which is not much different than a video player, which is not the only function of MythTV
Cool program. This looks like a perfect compliment to the digital lifestyle. If this were part of the iLife suite, I bet a lot of people would jump at it. If Apple had put it in iLife 05, it definitely would have justified the $20 increase in price, and it probably would have sold better and could draw more people to the platform.
The audio IS "speeded up", but the pitch remains the same. This is fairly easy to do with digital audio.

Or, if you're from the south, you can slow down the show for easier understanding.
Bah! I was going for a quiet weekend... Now I gotta decide whether or not my MythTV box needs an upgrade or not...
:)
ok what am I saying? Sounds like a fun weekend for me
"why don't you just slip into something more comfortable...like a coma!"
Not watch 24 at all!
I've got ya beat by 18 hours, plus I haven't suffered through a mindless, repetitive story about a guy who likes to yell at people.
Socialism: A feeling of discontent and resentment caused by a desire for the possessions or qualities of another.
I just got my MythTV system running 2 weeks ago. I'm still running 0.16 but it's still great.
I'm using a Pundit-R that sits beside my TV, and it uses a 802.11b wireless card to get programming data.
Since I've been using it for 2 weeks, it's totally changed the way the wife and I watch TV. We never miss an episode of our favourite shows, and never watch commercials.
The commercial marking function is like magic, it looks for blank frames in the data stream and flags that as a commercial. I'd say it gets it right 80% of the time, 15% of the time it will include the station ID clip, and 5% it will grab an extra commercial, but I'll just hit forward on the remote to skip it.
My favourite part is using it to watch a new show that's 'almost' live. I'll set it to record the show, but then start watching it 5-10 minutes after it's started. When I get to the commercials I skip over them, and by the end of the show I'll have hopefully synced up perfectly with the real time stream.
With Lokitorrents getting taken down today, and left with a rather tasteless warning, I wonder if the MPAA will start looking to litigate the source of illegal content, like MythTV?
Do you (slashdot readers) think it's a possibility?

Knoppmyth is the whole shebang. I based my dedicated install on it. http://www.mysettopbox.tv/knoppmyth.html
Disclaimer: I own a DirecTivo. I don't really know why I needed to declare that. I think I just wanted to sound important.
[1] Tivo is starting to look like it might become "beleaguered" much like Apple was declared during the years 1970 through 2005. Yes, Apple was called beleaguered by the tech media even before it existed.
[2] Tivo is (I think) Linux based. Making it compilable on BSD Unix is, like, what? Two man hours? What? Different motherborads? Ok, four man hours.
[3] Steve Jobs wants the Mac to be the center of our digital media warm fuzziness thing where we go for brief respites from the wacky demon haunted world in which we live.
[4] The Grammys have become dominated by hip hop and gangsta rap. Only a vast array of Mac powered DVRs spread across the nation can protect us from whatever.
It can't be any more obvious that that! You savvy?
You heard it here first.
The second rule of MythTV, you *will* fight with Tivo users. :)
If you are referring to KnoppMyth then it also installs the backend. You can use the cd to just install the frontend but it will install the both pieces on one computer. That is the way I have done it.
KnoppMyth definitely makes MythTV more accessible. The entire install and configuration takes about 20 minutes provided that you are using linux compatible hardware. Pretty much if you are using a Hauppauge card then you are set.
The answer to this at EFF:
"As EFF describes on our Digital Television Liberation page, recent regulations in the United States will ban the manufacture of DTV-receiving hardware described here after July 1, 2005. While we challenge these regulations in court, the clock is ticking, and it's safest to assume that it will be difficult to get unrestricted DTV receiving equipment in the future the way you can today.
However, despite the manufacturing ban, existing equipment will continue to work (and to be lawful to possess and operate); it will be immune from the restrictions imposed on future equipment. That means that the equipment you can buy today is more functional and more useful than what you may be able to buy after July 1, 2005."
...is that a lot of digital/HDTV cable customers will be able to use their digital cable box as a capture device, and plug into the MythTV back end host with firewire. This uses almost none of the host CPU as the cable box is spewing raw MPEG2 over firewire, and MythTV just needs to save it to disk.
That right there just tripled the number of channels I could record, and gave me HDTV capabilities as well as premium channels.
I'm one of the people scratching my head over why this was put in the Apple category where few people would see it. Most of the people running Myth are on PC/Linux platform.
Visit the EFF broadcast flag page, scroll down about halfway, and look under the Linux/Windows/Mac sections on the left.
KnoppMyth is probably the one you're talking about, but it's not trivial to setup. It's much easier than doing it from scratch and so long as you pick hardware that is receiving attention in the forums there, you should be fine, but there's a lot of options and configuration you need to do sometimes. A live CD backend wouldn't help too much, given that.

I've nothing to say here...
If by "fairly easy" you mean "there are existing algorithms that do this badly," then you're right.
If you mean "sounds exactly the same, only faster" then you're wrong. Considering the quality of these things now, I'm not sure I wouldn't rather just let the pitch raise.
The problem is how to represent pitch. Most of the time, this is done by converting to a frequency domain and doing a shift, or by convolving the signal with a waveform that causes a signal shift (the classical example of this is using a sine wave, as is done for RF encoding). The problem is that this technique is only really good for a signal that doesn't change over time.
In fact, even the best pitch shifters assume that the pitch can be modeled as function of time and are unable to deal with randomly changing pitches very well. Lots of artifacts are still introduced when dealing with an "instrument" as complex as the human voice (on the other hand, they work great for flutes). Of course, if you don't change the pitch very much, you can get away with less artifacts.
Mod me down and I will become more powerful than you can possibly imagine!

MythTV merely turns your computer into a VCR. The movie studios lost that battle back in 1984.
First if you use IVTV it does record mpeg. But besides that nuv is just an encapsulation for various diffrent encoding formats. So even though it says nuv the underlying encoding format is usally either mpeg2 or mpeg4. Now if you want to view them on other platforms mplayer has a patch to play nuv files. Also you could use winmyth to play them on windows. And if you want to easily convert nuv files to divx you can use nuvexport. Or you could play them through mythweb with mythstreamtv.
just because your a schizophrenic doesn't mean people arn't really out to get you
I never did understand why it's database driven. I first got into MythTV because I wanted to record shows at work (better cable service) and watch them at home - an never have figured out how to do it because of the database integration. I've been told Freevo may meet my needs better, but Myth is so nice...

pcHDTV 3000
This card is the successor to the original pcHDTV 2000. Its chipset allows you to record either standard over-the-air NTSC or digital over-the-air ATSC. I believe that drivers are in the works to allow you to record unencrypted QAM channels from digital cable.
Air2PC
This newer card allows you to record digital over-the-air ATSC. It allows you to record unencrypted QAM channels from digital cable.
From what I've heard, there's no clear winner for which of these two cards is better. The pcHDTV 3000 can be purchased at the pcHDTV web site for $189. The Air2PC is on sale here for $169. If you plan to purchase, do so before July 2005. After that date, it's questionable at best whether they will still be sold.
Search the MythTV user group mailing list archives for more information about these cards and support in MythTV.
I am concerned about any program, any piece of hardware, any treaty, any law that treats me as a consumer, not a citizen
Interesting thread. I looked into setting up MythTV a few months ago, but a few problems (me being a MS kiddie and knowing zilch about *nix, and being Australian, where the program guides were something of an issue at the time) foiled my attempts.
:D) have sinced moved to a new house, and the TV now sits in one of the spare bedrooms. Our antenna has several missing elements, so free-to-air TV is fairly unwatchable... so we download most of the TV we want to watch, and occasionally stream it via the xbox.
;)
My partner and I (yes, a girl!
End result? We watch a *lot* less TV. And... it's bloody great. We've gone from, say, 4 hours a night of TV - 28 hours a week, over 9 hours(!) of ads - to maybe 8 hours a week, no ads.
Break your TV. Cut off the cord. Move it to another room. Give TV a break... it's phenomonal what you can acheive without it - PetRescue is my example.
Finally, and a little more on-topic:
"timestretch" feature (for changing playback speed but not the pitch so you can watch shows more quickly)
So can you slow it down, for the stoners? Damn cartoons are getting too quick for me....
