Great, playback works this way, thanks :-) But the sound quality is
terrible - no comparison to playing the rtsp stream in MPlayer directly
or "encoding" the sound to pcm and playing the wav file. I have no idea
why...

And if I try

mencoder recorded_video_with_pcm_sound.avi -audiofile audiodump.aac
-audio-demuxer rawaudio -rawaudio format=0xff -ac faad -oac copy -ovc
copy -o video_with_original_aac_sound.avi

sound goes appr. 0,5 seconds ahead of video per minute (and the video is
not seekable).
