I own a ATI All in Wonder 128 card. Older but still does the job well.
One of the things I have really gotten into lately is recording from the tv to the Hard Drive. Ati's software has recording software, configurable for different mpeg levels and for avi recording.
The biggest thing that you want to know is: How fast is your computer, how big your hard drive is, and what do you want to record.
My computer is my entertainment centre. I own a 19" monitor, so I've been working on copying some older stuff from video to mpeg. I use mpeg level 1, settings set for a video cd. Which I believe is 352x240, 1 Mbit/second, sound at 22 Khtz, 16 Bit stereo. This is a fine setting for normal stuff, but it still is a space hog. Recording at that level is roughly 10 megs a minute of hard drive space. There is some visual degredation(blocking, possible skips in a camera pan)
If ClintonHammond has the commercial up, I recorded a commercial for our local pub which shows him playing music. Its about 2 meg I think. (can't really remember)Its under the clips section on his webpage here
If you are going to record, don't do it directly to cd. Take the extra time and steps to do it to the hard drive. Only because forcing it to go through the netowrk and CD at the same time probably would result in a loss of information being passed.
You might have to do a search on the net to find proper recording software, if you don't get some with the TV card.
My advice is try the recording of stuff to mpeg first, just various stuff. If you can alter the recording level, try it, play around and see what you come up with.
If you need more help, send me a private msg, and i'll see if I can guide you better.
