Okay, I picked it up today and have just spent the past few hours installing and playing with it. Price was $99 Australian, which is about $80 US. I got it from ww.i-tech.com.au.
First the negative. I installed it without problems into my Sony, then switched it to the Asus which runs SP2. It kept asking for an SP2 disk, so I said to hell with it and uninstalled SP2. After that there were no problems at all.
The card is light and moderately well made. It does get a little warm.
I tried the TV tuner first. All you have to do is hook up an antenna and press scan and it finds all your channels. My antenna reception sucks, but didn't suck any more with the AverTV. You can choose between antenna and cable tuners, but my cable is encrypted so I couldn't feed it straight into the card. The picture was very nice however.
Recording was simple, and on playback you get a nice PIP of what is on live. I didn't try time shifting. In Australia we have no electronic program guides, which is a bit of a bummer.
There are also S-Video and composite inputs, both of which worked as advertised, although the composite input needed to be seated just right or the picture would break up. The sound for the S-Video goes through the composite in, which is not explained in the manual. You cannot record copy-protected movies from an outboard DVD player, or at least I couldn't. I may keep trying though
The software is very flexible interms of encoding options, you can have MPEG1, MPEG2, and AVI and choose a range of settings for these up to raw AVI, or even have audio only in MP3 or Wave at various settings.
I had no problems with any of these except for the AVI encoding, which had artifacts and stuttering. I may need to play with these a little more.
CPU load ranged from 20-30% when simply watching the video feed to 45% when recording and encoding.
All in all it is a pretty good little unit, especially for the price.
Any questions, let me know.
