VDR does not record PS, but PES (PS is PES with an additional "pack" header which carries a SCR [system clock reference]). This is because the AV7110 does not handle PS playback, only PES. For PES playback, audio is synced to the video PTS, which is OK because the stream comes on-demand from disk so there's no problem with buffer over/underruns due to synchronization. For TS from air the decoder has to follow closely the timing of the transmitter, hence the additional PCR. If the PCR PID is not set correctly, the AV7110 will have trouble to sync audio and video, and may decide to run asynchronously. See iso13181-1 and iso13181-4 for details.
