[mythtv-users] cannot open /dev/video0

[Abigail Smith]

  I installed Knoppix-Myth on a 2 ghz pc with pvr-350.  I ran "cat /dev/video0 > /tmp/aa.mpg" and got "/dev/video0: no such device".  
   
  # ls -l  /dev/video0 tho does show the device file.
   
  The installation was done as root.
   
  Rsvp & thanks,
   
  Abby

"probe its inputs" sounds like you're trying to run mythtv-setup when 
you get this error? Try running it as root. It's easier than setting 
udev rules for permissions and works for most people (re: Jarod's 
Guide).
