VDR sends the PS1 PES frames with its AC3 payload to the
DVB card.  The firmware only forward PCM, AC3, and DTS to
the S/P-DIF out.  No way and no resources (memory and CPU
power) to filter or modify bigger part of the streams.
Currently only the first few bytes of the DTS/AC3 data
frames are checked to get the correct timings, data frame
size and sampling rates.
