And is there any hope of any enhancement?
I "need" the SPDIF of my Digifire 7.1 to be able to use the bitstreamout
plugin of VDR made by Dr. Werner Fink
(https://sourceforge.net/projects/bitstreamout/) because as he wrote the
SPDIF out of my DVB card is not "good":

"As long as the hardware on the DVB cards are not able to put
the 16bit none audio PCM data stream into a 32bit none audio
S/P-DIF transport stream all receivers which uses the bit flags
of the S/P-DIF transport stream for identifying none audio
loose.  All S/P-DIF data get from the DVB card to not have the
none audio bit set.  AFAIK this is a hardware bug (or better
this is the information I've got from TT) ..."

But when I try the plugin I got:

Mar 29 15:15:17 localhost vdr[9090]: S/P-DIF: Period size not available: Invalid 
argument
Mar 29 15:15:17 localhost vdr[9090]: S/P-DIF: unable to establish BitStreamOut for 
none audio PCM 
Mar 29 15:15:17 localhost vdr[9090]: REPLAY: can't open spdif interface

I am using CVS of driver/lib/utils from yesterday...

Any suggestion?

Thank you very much,
