I'm looking for some help from a myth developer.  I think I've hit a 
wall in what to look at next.  I'm pretty sure the problem is with the 
FFmpeg update going from Myth 0.24 to 0.25.  I was able to track down 
the error code -541478725.  It's AVERROR_EOF.  With SD recordings on 
0.24 I get only one of these errors at the end of mythcommflag which 
makes sense.  On 0.27 I get a whole bunch of these errors and then 
mythcommflag quits.  It quits in much less time than on 0.24 and doesn't 
find any commercials.  It's almost as if FFmpeg doesn't know how to read 
an SD recording from a PVR150 correctly any more.  What's strange to me 
is playback still works fine.  Could someone explain why I get so many 
-541478725 errors?

Thanks
