Hi,
Just an additional info for the ones who want to help - the
pvrinput-plugin passes through the TS from the HD PVR to vdr, there's
nothing changed.
So hopefully the plugin is not the one to blame for... :-)
I posted a sample PAT and PMT of the HD PVR in february, perhaps it can
be used to clarify something.

How do you create the PAT and PMT files and then understand them.
I'm pretty sure that sample file was only mp3 input instead of AC3
digital which is what I use now..

Hi Guy's,
How do you go about understanding AC-3 within a VDR context?
(apart from reading up on it online - which now has my head spinning).
I have a Hauppauge PVR-HD and two ATSC cards. The ATSC cards work as
they should and with the new atsc/dn patch on
1.7.15 now have the correct dpids.
However, if I turn on add new transponders or update pids, then my
Hauppauge PVR channels lose their dpid values..
Sep 1 19:10:33 oac vdr: [8186] changing pids of channel 920 from
4113+4097=27:0;4352=...@106:0:0 to 4113+4097=27:0:0:0
If I keep automatic channel updates off, then xineliboutput and
streamdev work for these channels, but vdr-vnsi (xbmc)
and vdr-xine don't (no audio)..
I'm assuming vdr parses the ac3 headers in some way and sends
information onto the playback frontend. How would I go
about seeing what those headers might be and looking into patching
pat.c accordingly?
I noticed all the comments about e-ac3 and wonder if a similar patch
should be made for this device.
As an aside, vdr recordings from these channels play back fine in
vdr-xine.
So, more specifically, I suppose I would like to know how to find out
the STREAMTYPE:
I'm pretty sure it falls under this:
case 6: // STREAMTYPE_13818_PES_PRIVATE
But I'd be interested in seeing the flow through this section of pat.c
and what is happening.. Mainly to see if
something needs to be forced on?
I can create a five second VDR recording if someone wants to see what
the TS stream looks like.. But I'd be interested
in diagnosing it myself..
Thanks.
