try this:
 enable embedded teletext (ivtvctl -x 1 -b teletext), then run 
'cat /dev/video0 >/dev/video16' and then run 'util/vbi /dev/vbi4'. vbi4 is 
the device that outputs the embedded VBI data. The PVR-350 is responsible for 
extracting it from the MPEG stream, and the driver transforms it to the same 
format as /dev/vbi0. 

the vbi-passthrough done in util/vbi is not yet integrated into mythtv 
playback. Guess we just have to look in the util/vbi passthrough routine and 
copy-paste the it somewhere in the player (avformatdecoder).
