[mythtv-users] mythtranscode / nuvexport

[Jeff Dill]

I just upgraded from RH8 to RH9, and when everything was re-installed 
again, I started seeing this too.

I am using the latest CVS from both MythTV and ffmpeg, plus I tried 
ffmpeg sources 0.4.8.  Both produce the same results.

Every file I have tried to convert a valid .nuv (both with nuvexport and 
my home-rolled scripts), the video gets stuck at frame 3 and audio 
doesn't do anything. Mythtranscode spews messages that "Audio is XXms 
behind video at # 3" with varying values n place of the XX.  Sometimes I 
get messages "Fast-Forwarding from 0 to 0" on a file that has 
commercials marked.
