What's the video source? PAL has 576 lines maximum, NTSC 480 or so. And
1024 pixels across is well above "TV" bandwidth (even DVD).

V4L and V4L2 is the usual video API. bttv is a well-developed driver for
these APIs, supporting most "non-intelligent" capture cards like the
Hauppage etc. See www.bytesex.org.
Around also is the Kfir card - www.linuxtv.org. But I don't think its too
mainstream.
There are drivers for the Pinnacle DC10+ - which has hardware MJPEG
compression. I have one of these too and it is very easy on your CPU, but
MJPEG makes mega-large files compared to MPEG.
Hope this is some help,
Steve
