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.

Regards
Ravi
