The audio is put through to DXR3's SPDIF out.

The problem stays even if I disable digital passthrough and even if I 
use my soundcard instead of DXR3 audio. I guess this is bad...
As far as I remember, this problem started with Xine 0.9.5.

With this configuration, the audio is still the bit ahead.

With software decoding, the sync is absolutely perfect.

Concerning James' post in the devel list: I will try the CVS "dvd" tag
