[mythtv] Playback-problems using latest cvs

[Jan Fengler]

Hi There!

The Problem is, that the playback is too fast, the time-stretching function 
doesn't work (no changes, regardless of wich factor i set). Changing the "use 
video stream as timebase" changes between "Audio buffer overflow, 
audio data lost!" (off) and "prebuffering pause" (on) Messages from the 
frontend. The recorded files are ok, i tested it with mplayer and 
mythtv-0.15.

Thanks for your attention
