Yes, and it seems to be a XVMC problem since you said it works with XV 
and software decode?

The bug was previously hidden because the recorder was "limited", but 
that's not a long term solution. If you haven't already done so, please 
try and get some logs and more info on what's wrong with XvMC and open a 
bug for it.

For a quick workaround, you can try activating "hw decoder" for your DVB 
card. As a side effect (besides using different demux settings) that 
should limit your recordings to just one audio stream again...
