TV Tuners For The PC: Internal Or External
~*77*~ writes "TV tuners are gaining popularity for simple TV watching on your home PC, as well providing capturing capabilities intended to rival Tivo style devices. BigBruin.Com has new reviews taking a look at two TV tuners in the $50 range... An internal, PCI device from Leadtek... And an external, USB 2.0 device from Transcend... Head to head testing decide whether either is worth your time or money."
For anyone with a TV card, I recommend trying DScaler - it's open-source software which can filter and display video inputs, particularly from TV cards. I've been using it for the past four years, and it's far better than the TV viewing applications that came with my Hauppage WinTV card, or my friends Pinnacle PCTV card.
I have an ATI Radeon All-In-Wonder 9800SE, and I'm not really all that happy with it on the tv tuner front.
In my experience, the ATI drivers are somewhat buggy and temperamental on Windows, and worse on linux. Also, I'd love to use Videolan, but it's never worked fully with the AIW. The most recent release is actually able to use my AIW, but only the antenna signal, not the composite, so it can't capture anything from satellite or cable boxes plugged into it. Obviously, that's more of an issue with Videolan, and hopefully it'll work some day soon, but if you wanted to use Videolan with a tv tuner card, it's something you might want to consider.
That's not to say the AIW is bad, and for the price I paid I'm generally happy with it. It does do the job. Usually. But if I had more money, I would definitely have gone for a seperate tv tuner. If nothing else, it's more flexible - you can upgrade the graphics card without worrying about the tv tuner card at the same time.
I had used many tv-tuner cards (ati, leadtek, hauppage, and etc.) and one I thing I could generalize is that the software (drivers and tv proggie) for these cards suck. Almost all of them have these fancy UI that never conform to any standards or sometimes even common sense (what's up with the blinky lights in leadtek programs?). Also, the limited feature set for basic tivo-like functionality. I found a nice free program called DScaler (dscaler.org) that offers a lot of features for and it's compatible with most cards. It's still in beta the last time I checked though.
For recording shows I like using a ReplayTV(a TIVO would do), then you can connect to it over the network and play your shows on your computer.
For those not familiar with DVB, this is used in Europe for satellite and terrestrial TV transmission. There is no open DVB used in the U.S.
But, we have ATSC, the new digital television standard, which broadcasts MPEG2 streams that are easy to record & play.
ATSC has the big advantage that it supports HDTV transmissions, and there is a ton of HDTV programming available. I don't think HDTV has moved past early testing phase in Europe.
Don't use the given software, use DScaler or Virtual Dub.
There's two types of TV tuners out for PCs right now: Those with hardware encoders, and those without
The cheap ones (usually under $50) do not come with hardware encoders.
Hardware encoders (usually MPEG2) look superior and are generally smoother, taking the load off your CPU. Do not assume that since you have quad-processor super PC that it's enough to output great/smooth video. A hardware MPEG2 encoder is still superior.
As for internal VS external, there's a few USB 2.0 tuners with built-in hardware encoders, but none of them work in Linux. You're better off getting a Hauppauge WinTV PVR-250 (or 350 if you need TV-out) and sticking it in a MythTV Linux box... The current king of Tivo-like software.
