[vdr] playing two audio streams at the same time

Hello,

Is it possible today with vdr, to send one audio channel to the headphones and the other audio channel to the speakers (or another headphones)? (it wasn't possible about 4 years ago)

Example: we watch a film recorded from Arte, and my wife wants to listen to the French, and I want to listen to the German audio channel.

If it's possible, what version do I need at least and what must be configured?

If not, what would be the effort for a VDR developer to implement such a feature (in hours, $, € or whatever)?

Or do you know other free software for watching and recording TV, with such a feature?

TIA for any hints!
