Well, have done some testing today and found out that mp3 replay
fails if you have replayed a dvd or a recording with the new
ac3out via DVB (this means something that uses LCPM audio)
before. You have to start a normal recording (without ac3) to fix
this.

I have included an experimental patch against mp3 0.36 which
fixes the problem for me. I cannot explain why this works, as
the additional commands doesn't make a logical sense. May be
this all is cause by the weak LPCM implementation in the driver.

Could please everybody who have the replay problem test the code
and give me a note.
