I've run into something similar, and it had to do with audio. 
Apparently, if it's misconfigured, the device doesn't send any output at 
all. I found that this helped (in rc.local):

   /usr/bin/v4l2-ctl --device /dev/video0 --set-ctrl=audio_encoding=4

Also, in mythtv-setup, go in and reselect the appropriate audio input 
method. Changing OS versions can mean subtle changes in the notation of 
the input ports, so Myth might be trying to use the wrong input. Even if 
you had a working value before, it might have changed.
