[mythtv-users] ivtv headaches

I'm having an incredibly difficult and frustrating time figuring out how to 
solve a problem I'm having with my pvr-150 capture card. For some reason, my 
ivtv driver does not seem to work most of the time and I am usually met with 
the I/O error when I try to run the 'cat /dev/video0 > 
/video/buffer/test.mpg' command. As per the ivtv faq, I'm assuming it might 
be an error that is correctable by unloading/reloading the module. 

However, whenever I try to 'rmmod ivtv', I am told 'ERROR: Module ivtv is in 
use'. I have made sure that mythbackend is not running, just in case that 
was screwing things up. upon examining the output from lsmod, I can see that 
the info for ivtv is:
"ivtv 1331396 1"
from what I can gather, the use count is still at 1, but I have no idea what 
is using it, so I can't find a way to reload the module. Any idea how I can 
unload the module so I can reload it? btw - I have tried rmmod with the -f 
and -w flags to no avail.
