Well, I wouldn't know how!

Are you saying VDR should set VPID, APID _and_ PCR-PID when recording?
Would it then receive extra TS packets with the PCR-PID?
What should it do with those? Would they have to be used when
converting TS to PES in remux.c? What if PCR-PID == VPID?

So far for channels where PCR-PID == VPID things appear to work fine.
Since Oliver Endriss' driver fix live tv as well as replaying recordings work
great. So apprently in case PCR-PID == VPID there's nothing else VDR
would have to do, I guess.

What's the reason to have an extra PCR-PID, anyway?
