Ok, so you've got the udev rules making the appropriate symlinks, you've 
verified that the 'mythtv' user is indeed a member of the video group,  
and the device nodes have the appropriate permissions (eg, read/writable 
by the video group).

I guess that leaves a couple things: what exactly are you entering for 
the path to the device in mythtv-setup, and who are you running 
mythtv-setup as?  Are you logged in as the 'mythtv' user, or are you 
logged in as someone else?
