On two occasions earlier this month I asked a question about why
v4l-conf (and therefore xawtv) was all of a sudden failing with the
following error: "can't open /dev/video0: Cannot allocate memory".
Well I re-read your post and realized I probably misread it. The
app actually can't open /dev/video0 ?
Could this be a simple permissions problem? Try it as root and see what
happens. I had trouble with PAM and the NVidia driver (briefly :-) )
This is just a thought though... I'm not a developer...yet.
