Hi, feedback: have just tested the patch with DVB and it seems to cause 
live tv audio to stutter (like when the sample rate is incorrect and the 
buffer keeps over/underfilling).  Could this be caused by the issue that 
you note above?

Also, the watch recordings screen bails out immediately that it starts 
trying to play the thumbnails.  I didn't look too closely other than to 
note that it was running the PosMapFromEnc function (I think?).  
However, I haven't cleared down my old position map table, so this may 
be part/all of the problem.

Recordings DO seem to play back ok using "mythtv blah.nuv"

Will dig a little deeper as time allows.   Thanks for the patches Doug 
(and Isaac)
