[mythtv-users] PVR-350 Almost Working?

Here is my latest attempt that seems successful outside of Mythtv.  I can
run mplayer /dev/video0 and change channels via ivtv-tune.  I reconfigured
mythtv-setup by deleting all cards and related info.  I picked the mpeg
card instead of the analog one that comes up as a default.  Note that I've
chosen  an older version of the encoder firmware that appears to work
better.  Should I be selecting /dev/video0 or /dev/v4l/video0?  I've
included the errors from the terminal window when I try to watch live tv. 
Any theories?  Will the ivtv mythtv patch do me any good?
