Since VDR version 1.7.12 the PCR packets are recorded and replayed, and
also used in Transfer Mode:
2010-01-31: Version 1.7.12
- The PCR pid is now recorded for channels where this is different from the video
PID. To facilitate this, the interfaces of cTransfer, cTransferControl, cRecorder
and cReceiver have been modified, so that the PIDs are no longer given in separate
parameters, but rather the whole channel is handed down for processing. The old
constructor of cReceiver is still available, but it is recommended to plugin authors
that they switch to the new interface as soon as possible.
When replaying such a recording, the PCR packets are sent to PlayTsVideo()
