Well that's no biggie in my opinion, i would do playback with the HW+ Card
or burn it to DVD and let my Yamakawa do the playback :-)
But of course it would be nice to have AC-3 playback in VDR too.
When reading the opeinion that the DVB Cards are not able to playback AC3,
then i sometimes ask myself if this is true, did you follow the *same*
discussion about the D-Box 1 ???
Now due to a New Firmware ( Dr. Overflow alias Uli ) it CAN passthrough raw
SP-Dif, so it WORKS ...
I wonder if the firmware guys could teach this to the DSP (?!?) in the DVB
Card too ...

The other possibilities for you would be to playback AC3 via Soundcard with
SP-DIF ( Like SBLive or Terratec 512i ) or via Hollywood+ MPEG2 Decoder Card
SP-DIF ...

Thank you for those news, i hope you get VDR stable with the new API so we
can see all your NEW ideas becaome real :-)
