[vdr] 1.7.1 + multiple audio streams on channel = buffer problem

Hi,

I'm with 1.7.1 and observe some buffer problems on channels with multiple
audio streams.
Bandwidth of audio steams probably make a different since I observe problems
with channel that has
6 audio tracks or even 4 audio tracks, while there are other channels with 4
tracks that have no problem at all.

I guess thats a result of moving to TS.
Any hint what buffer should I increase?

VDR log shows the following:
