Good! And good luck. Since there is no error message logged. As noted, 
the only thing is the '/dev/nvidiavideosync device missing' error (can't 
remember the exact device name, but since it does not exist, that's not 
much of problem: whatever is missing, will not turn up!).

And, as noted, analog plays, but digital does not, so it probably 
relates to differences in mpeg2 versus moeg4 decoding, and how that 
changed from say SVN 18408 (actually it might have been 18468...but it 
was 2 schema updates prior to 19110...which is broken.

Since I have 400+Gig of recordings, I don't want to dump the database 
and do a downgrade...Thankfully I can make it to Monday when my cable 
arrives and I can install the nvidia driver and new card...Crossing 
fingers, legs, toes and eyes!

Apropos of nothing, are there any scripts around which would downgrade 
the mythconverg database? It should be possible, even if slightly complex.
