It would be interesting to know specifically which parameter is at
issue. Is it really that CC fails if capturing with a video width
other than 720? Also, is the video corrupted if you just do a "cat
/dev/video0 > out.mpg"?
I'm not confident I can fix this, but at least if you can narrow it
down to a lowest-common-denominator use case which demonstrates a
driver bug then you can take it to the ivtv-users mailing list to see
if perhaps Andy Walls could take a look.
