[mythtv-users] Stuttering/A'V out of synch, but only after fast forward.

[Henrik Bentel]

Pause/unpause doesn't seem to fix it.
Don't know about words being mis-ordered.

I'm not sure it's the audio anymore. I went tack and tried the Alt-TAB
trick on some
recording that had much higher bitrate (like 5000) and the Alt-TAB
trick doesn't fix
it this time over?

In case someone can read the verbose log I've attached a snippet of 
the output when the stuttering is going on. This is with '-v all' set.
