I'm pretty sure that there won't be drop-outs with soundcard
output. Certainly this can be done. You have to setup the audio
device and pipe the data to it (resampling should not be
necessary). This all has to be done from inside the MP3
playbuffer.

Of course I will accept a patch for this, but I cannot give much
help for this as my VDR machine lacks a soundcard.

Well, you have VIDEO distortions with the OSD open. Additionaly PCM audio
has a higher data rate as the DVB audio. And finally the PCM
driver support isn't very good anyway.
