You need to convert it to a program stream. 
Use the av_pes2ps tool, which was discussed here before and tell us if
the result works with the players you have.
We only tried it once with "powerdvd" under windows and it worked.

The MSP34XX series of chips are sound decoders for analog TV/radio.
Some also have analog sound and video switches.
The analog upgrade module of the DVB-C card has such a chip.
There is no use for it with a DVB-S card.

No, it is because dvdplayer does not send the sound to the DVB card.
The DVB card cannot decode AC3 but the decoded PCM stream can be sent 
to the card as a PCM-PES with the firmware version that came with 
DVB-0.7.0 (and later).
I know I donīt write much in the DVB/NEWS file but this is in there.

Until support for this is in dvdplayer (I donīt know if this is
planned?) you will need a soundcard.
