As I said: the first audio is recorded as 0xC0, the second audio as 0xC1
and DD as 0xBD packets. When replaying, VDR filters these out again (see
the related code in VDR/dvbapi.c).

There is code in VDR/dvbapi.c that detectes the audio packets.
Just take a look at cReplayBuffer::StripAudioPackets().
