[vdr] Missing sound..

[JJussi]

Hi!

I have my vdr with DVB-C cards at livingroom and now I build other vdr 
(without cards) to bedroom and use NFS to connect to video directory.
When I try to play recordings, everything except SOUND is fine..  I get 
following error:

ffmpeg_audio_dec: increasing buffer to 98304 to avoid overflow.
ffmpeg_audio_dec: trying to open null codec
audio_decoder: no plugin available to handle 'MPEG layer 2/3'

What libs (or something) I miss?
