[mythtv-users] Upgrade and problems with 32kHz audio

[Ray]

I recently upgraded to the latest Mythtv version and I'm having problems 
with some of my older recordings that were recorded with an audio 
sampling rate of 32000 Hz.  These are Mpeg4 files from a bt878 card and 
probably using btaudio (they were recorded back in 2003 & 2004).  The 
videos play fast and the audio sounds like chipmunks.  My recent 
recordings done with a PVR-500 card play just fine.  I tried transcoding 
one of these problem videos with a profile that specifies 48kHz audio 
sample rate but mythtranscode just copied the audio.  I've tried setting 
playback to "use video as time base but that didn't help either.

Is there anything I can do to either get Mythtv to play these shows 
correctly or to transcode them into something Myth will play?
