Assuming that "mythtv" user is running mythtv, and not in the
"video" group, it is probably access permissions.
You can test by "chmod 777 /dev/video*" and see if you get
any permission problems.

I'm lazy and have permission problems like this constantly.
Rather than fix them right I just do this in my rc.local:
chmod 777 /dev/video*
chmod 777 /dev/dsp
chmod 777 /dev/mixer
chmod 777 /dev/sequencer
chmod 777 /dev/sequencer2
chmod -R 777 /dev/snd
chmod 777 /dev/audio
chmod 777 /dev/adsp
chmod 777 /dev/ttyUSB0
chmod 777 /dev/ttyUSB1
chmod 777 /dev/ttyUSB2
