As far as I can see VDR extracts all packets delivered by the driver under
the dolby digital PID and sends them to the command defined by the "-a" option.
VDR does not do any additional conversion or manipulation with these packets,
so if any such measures are necessary, somebody will have to tell me what that
would be.

I believe it is 1283 (decimal). But there have been reports saying that
the DD data delivered by Premiere is broken...
