Hi Andy, I compiled and installed this version and it worked like a charm! Thanks a lot. - Recognizes the correct card, chips and tuner (dmesg) and no errors in initialization - Checked composite and tuner inputs with /dev/video0, both are functional - Composite input gives decent picture quality (although there seen to be some minor artifacts at edges of red/yellow in all players - but maybe this is the best that can be expected from this capture card?) - Tuner input - can get a picture, but has color artifacts, even after fine-tuning frequency with ivctl. Are there any settings for color sub-frequency etc I need to tune? I am using India Cable, so the frequencies and sub-carriers may be different. In any case I do not plan to use the tuner input, but can test and report back on any experiments if needed. - S-video input - not checked yet, will do this later after getting an S-video source - Audio - it came up briefly, but missing again now. I may need to check all the other system settings for this one.
