VDR-VNSI3 0.9.1 stutters on some channels

Hi,

Fernetmenta, thanks for all your hard work in XBMC and VNSI.
Opdenkamp asked that I log this issue I'm am having here...

I quote:
[16:36] <opdenkamp> looks like an issue that i'm sometimes seeing with tvheadend too but haven't looked into it yet. the audio stream is "missing" when starting playback, video buffer goes to 100%, playback starts, and *poof* suddenly there is audio data. player then tries to sync and fails.
[16:37] <opdenkamp> tvh and vnsi use similar code here, so there's a chance there's a bug in there, or a bug in the pvrdemux code in xbmc
[16:38] <opdenkamp> some race condition most likely

Stuttering occurs on multiple vnsi clients. The ones I have tried are Openelec Generic 3.0.3 , Openelec RPi version devel-20130607055706-r14591 and also XBMC 12.2 running on Windows. All encounter the same stutter on the same channels while other channels work fine.
The stutter occurs running VDR 1.7.31 and VDR 2.0.2 with vnsiserver3 (0.9.1).

I found that compiling and installing the old vnsiserver (0.9.0) fixes the issue.

Any ideas?
