I am currently working on making the switch from PES to TS
as the VDR recording format, that's why there are currently
no new versions of VDR.
However, since the German ARD channels are going to start broadcasting
the standard AC3 component descriptor some time next week, I'm
publishing the attached patch that implements this in VDR 1.7.0.
From what I have been told, Premiere was the first provider that
actually broadcasted AC3 audio, and they chose not to use the
standard stream content value of '4' ("AC-3 audio"), but instead
used stream content value '2' with component type '5' ("MPEG-1 Layer
2 audio, surround sound"). And since they "certify" all their receivers,
this wrong decision was quickly adopted by other broadcasters, and
became a "pseudo standard".
Note that this patch is not necessary to receive AC-3 audio on the
ARD channels. They will still be broadcasting the old descriptors
in parallel with the new ones for about a year, so existing VDRs will
work just fine. This is just to let people who like to test this
actually do so.
The channel

already broadcasts the new AC3 descriptor and can be used for testing
(no video, just audio test tones).
