More findings: I also tried dvx-cvs from yesterday. While OSD is much better,
I now have other troubles:

The stuttering is even worse on ch switch and happens more often in between
(even with bigger buffers). And audio sync is very bad.

But, if I use NPTL, both are not a real issue anymore. And vdr is much more
responsive. I just don't know how stable vdr is with NPTL. At least I can now
start vdr with nptl whcih wasn't possible with dxr 0.2.2.

The progress is really nice!
