I just would like to have the possiblity to record DD and have my sound
output analog at the same time.

The dvd plugin as of now is broken regarding audio I think. It should be
able to downmix DD tracks to 2.0 in order to get analog output. That's
why it has a52dec as a dependancie. Right now it doesn't work (VDR
1.3.23 and dvd plugin CVS). Also changing audio tracks doesn't work
right now.
