Check the console and dmesg for closed captions or vbi messages.  TVTime 
makes clear a bug in the bttv kernel modules where if it fails to read 
the closed captions or XDS it goes black/red.  In TVTime you turn xds 
and closed captions off.  In mythTV I didn't look around too hard, but I 
couldn't find a way to turn those off, so I made a fifo ( mkfifo /fifo ) 
and pointed the vbi device in the menu to that.
