post-install ivtv /usr/local/bin/test_ioctl -d /dev/video224 -u 0x3000
--------------------------------------

doing: 
dd if=/dev/video0 of=test.mpg
14316+23 records in
14327+0 records out

and the test.mpg looks just fine...

perhaps the /dev/video dir is bogus???

Ok, for starters, get rid of /dev/video/video0 -- it's plain wrong.

Should I assume that input works?  If you do:

dd if=/dev/video0 of=test.mpg and ctrl-c after a few seconds do you get a mpg 
file with anything in it?
