I'm not using any xine related functionality with VDR, but I tried the patch 
below.

Unfortunately it makes things even worse for me with Amarok than vanilla 
1.1.9.1 - with vanilla 1.1.9.1 audio was ok until I tried to play a radio 
stream, then nothing until restart.  With this patch, the same breakage 
appears to occur much more frequently, looks like audio gets lost when trying 
to play a 2nd song after a fresh restart (quickly tried in a session where I 
first played a MP3 (success), then tried a FLAC (fails), and everything else 
fails after that, no need to even involve radio streams).

Reverting this changeset fixes these problems for me.
