Building A Low-Budget TiVo Substitute?
thepuma writes "Since I'm cheap, and don't want to pay monthly fees to Tivo, I am researching building my own low-budget Personal Video Recorder and player. Free software options include Freevo and MythTV. Hardware options are the main cost factor. How would you go about building the perfect low-budget PVR?" We've looked at similar questions before, but the guts of such a system (both hardware and software) have been improving -- MythTV, for instance, now supports Hauppauge's PVR-350 card. How would you build a system like this now?
Don't try to use one of these projects because you think it will be cheaper.
If you want to do it because you think there are other benefits, or because you like to tinker, go right ahead.
You will spend more than the cost of a Tivo plus lifetime service by the time you are done, though.
Compared to a Tivo: You have to switch tapes They only hold 8 hours You have to rewind them It's a pain to find that 30 min show in the middle of the tape They're louder (at least mine is) when FF and Rewinding Tivo has automatic scheduling
I'm sure there are other advantages, those are just off the top of my head.
Tapes have the advantage of being portable and everywhere so you can take what you recorded to your buddies house, but overall Tivo or some other similar DVR blows the VCR away.
Minimum spec on a PVR is a lot more than a celeron.
For instance, for the SageTV thing mentioned earlier they state:
MPEG 2 capable receiver (the ones listed on sagetv are analogue ones... really you need one that can do satellite or at least DVB) - minimum $100. To be the same quality as Tivo you'd need one that's RGB in and oh dear they don't exist.
PIII-600 256M - $100ish depending on where you get it.
Video card with TV Out - $50
Big hard drive - at least 120GB - $100
That's $350 *before* you've put in the cost of the rest of the PC... Shuttle cases for example are $100 a throw.
Then there's the noise factor. Tivos are whisper quiet... To make a PC that quiet wou can easily add another $100 onto the base price.
Simple math, but how much of the 300 watts is used for an idling PC
There's no way a PC without a monitor is going to draw 300 Watts unless it's a specialty super-computer. (i.e. Runs at 100% CPU power at all times, while making use of heavy draw hardware such as GPU rendering.)
150 Watts is a much better average. 24 hours a day, with ~30 days in a month, at 150 watts gives:
24*30*150 = 108,000 Watt-Hours = 108 Kilowatt-Hours
Look up what you're paying per KW hour and multiply that by 108. For example, 10 cents per KWH gives you a monthly cost of $10.80.

It has:
Those are the bare neccesities if your just going to be cheap. I am cheap/poor too, so that is all I have. Someday I'll get a nice DVD burner so I can archive stuff I might want to see again somday. I also want a wireless keybaord.

They have a page with some nice installation guides:

As you can see I am all for building a MythTV box, but having built one, I have to warn you that the software isn't perfect yet. It really kicks Tivo's ass in terms of functionality (I love the MythWeb interface, and you can set it too completely cut out commercials, which it does surprisingly accurately), but it still can be a little buggy sometimes and should only be used by people who like to tinker.
I've always maintained that buying a real Tivo was always the cheaper option, especially if you count the costs of your time involved. Now, even not counting those costs the commercial product is much cheaper! If "cheap" is really what you want (as it's listed in your request) then you really need to look at it closely.
With a new account (1 year contract) at DirecTV or Dish you can get a free or cheap PVR included... and many other benefits (3 rooms, free installation, etc. etc.). Certain plans (Platinum level or some shiiiiii) even give you the PVR subscription fee included (or included in your receiver mirroring fee).
I'm not saying you shouldn't try building one yourself, but the argument was usually "I could build one cheaper with parts I have lying around" however most people then went out and spent $75-$100 on a brand new capture card. With subsidized
MythTV has definitely progressed along the years, but it's still not 100% reliable (what open-source anything ever is truly complete, tested, and waranteed). That being said, it definitely has some other cool "Media" functions that I really would like in my family room. Of course, I'm not willing to live with the ugly beige box and noise (before you say silent processors and slimline cases, add those costs to your initial argument).
If I truly had the hardware lying around (I don't) and I truly wanted a project not just the end Tivo functionality (I don't) and I was willing to put up with all the tinkering and annoyances required (I might be, wife definitely isn't) then I would consider doing it.

"Funny," perhaps. But "insightful?" I've wiped more insightful commentary from the bottom of my shoe.
Now, if "How can I pirate TiVo's service to use on my non-TiVo box without paying for it, I could see where this comment would be appropriate. But just because TiVo is Linux-based, anyone who looks for another solution is somehow a hypocrite?
For shame, Mr. Coward, for shame. And you wonder why mom always liked me best?
The way I see it, TiVo has three components: The hardware, the software, and the subscriber information stream. The hardware is basically a small computer with a big hard drive, and its primary advantage over a beige box is a quality I like to call "Media center friendliness." Oh, and it comes with a remote rather than a cron daemon.
The software consists of the Linux kernel and some schnazzy proprietary interface software. The latter is what adds value to the product for most users.
The subscription information is the final piece of the whole TiVo experience, because it gives the box the ability to find stuff for you even when you didn't know it was on, and make recommendations.
So let's get this straight: TiVo provides a certain experience, but not everyone wants precisely that experience. There are plenty of reasons someone might want to build a computer with some of the capabilities of a TiVo. For example, they might want the PVR capabilities but not the features that rely on the subscription stream. Or they may want to be able to back up shows onto DVD, or rip DVDs to the box, or use the box as an all-in-one PVR/DVD player/router/firewall/webserver/gaming platform, just so that they can turn the whole thing into a flaming pile of silicon by getting it Slashdotted while it's trying to record "The Simpsons."
That's what I'd do, anyways.
You want the truthiness? You can't handle the truthiness!
And at the end of a month, he will probably know a thing or two about managing video streams, caching, fs tuning, how TiVo works in the first place, and probably a thing or two about building small databases with large BLOBs attached, and maybe start figuring out how to network the FreeVo together with the rest of his LAN so he can watch CNN from his laptop on the porch.
At the end of the same month, however, one who just buys a TiVo will probably know how to watch television.
Whatever happened to taking on a challenge just because it's there?
This is not my sandwich.
