I currently have a cheap-o PCI capture card that doubles as a TV tuner. The thing only cost me about thirty bucks, and I knew it was going to be fairly crappy; but it was all I needed at the time.
Now, however, I'm building an HTPC (as indicated in the 'My Refined HTPC Build' thread), and I want a fairly decent, low-profile PCI-E card that can to the following:

By the way, through standard Component, what is the resolution Component broadcasts at? I know it's not as high as Composite, but I'm pretty sure Component doesn't broadcast max at 320 x 240, which is what my capture card software captures raw AVI input as. (actually, i can use the MPEG-2 encoding at 640 x 480, but the recorded file has highly noticeable compression artifacts).
Or is this problem merely caused by the severely limiting 133MB/s bandwidth of the PCI slot? I know that raw AVI files at 320 x 240 go about 26GB an hour, so I think that's why. Not sure though.

- Capture Component input (the yellow video cable). Sound will be handled by the onboard sound, or more probable, a sound card.
- Properly tune into Rogers Cable. I'm still on analog, I'll worry about the switchover to digital when the time comes. My current card displays snow artifacting in all channels (meanwhile a direct connection to my TV works fine, so it's not the cable). I want something that can keep the cable input in it's highest quality.
