hmm, 360 is not a multiple of 16, nor is 360/240 == 4/3. sure you don't mean 320x240? > It must have only been a limitation of the various cards I could find > info on. > > I should perhaps clarify that this limitation only applied to the video > input from the external video connectors, not to the tuner output, which > could be recorded at full resolution on all the cards I looked at. > That may not have been clear from my use of the term 'incomming video'. > > Could you perhaps point me at cards which you know can capture at full > res from an external input?

I'm pretty sure I've used both ATI TV Wonder VE and Zoltrix Genie TV/FM to capture from composite input at 640x480 (NTSC, I live in north america). -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
