Hi,
when my understanding is right, I have to set "UseDolbyDigital" to no, when viewing dvds with non AC3 playback equipment. But with this setting when a recording starts while viewing dvd, there will be no AC3 track recorded.
Shouldn't there be a separate option in the recordings menu for filtering/selecting PIDs to record ?

The DVD plugin should offer both, an MP2 and an AC3 track.
After all, you might also want to replay a DVD with just MP2 sound even though you _have_ DD equipment.

DVD's do not include any MP2 but AC3 tracks ... and sometimes DTS and/or PCM tracks.

But the DVD plugin does work without DD equipment, doesn't it? So it must be able to provide audio data (be it named whatever it will) that can be played with the normal, full fetured DVB cards. That's what I was referring to.

DVD's in the PAL/SECAM area can include MP2 (MPEG-1 layer II) tracks, as well: http://www.discusa.com/technology/dvdvideo/dvdvid_audenc.htm

When I create a DVD using vdrconvert, I have the vdrconvert.env settings like this (because I want to keep the DVD small):
--SNIP--
# pids to use DVDUSESTREAMS="apid1:mp2+en apid2:mp2+es" #DVDUSESTREAMS="dpid1:ac3+en apid1:mp2+en apid2:mp2+es"
--SNIP--
I am assuming that this gives me a DVD with two mp2 audio tracks. Before the AC3/DD enhancements were added to vdr, I was able to switch between the two mp2 audio tracks on the DVD using the DVD plugin (while pressing the "1" key on the remote). But, now, with the new AC3/DD additions to vdr, after the DVD plugin detects the available audio tracks, it is unable to select between them.
Best Regards,

Yep, via a52lib it produces a PCM stream.
So it must be able to provide audio data (be it named whatever it will) that can be played with the normal, full fetured DVB cards. That's what I was referring to.
PCM is not MP2, but on of the private streams using the sub audio ID 0xA0 upto 0xA7.

Well, whatever...
The DVD plugin should deliver both streams.

I've a few of DVD's of this area code. No one of them uses MP2, many of DTS and some Video DVD with Music PCM and DTS 24/96. AFAIK DVD have to had an AC3 track accordingly to the specs. The rest is optional.
Beside this most of the AV receiver can not handle MP2 audio. OK, my Pioneer can do but without autodetection as done with PCM, AC3, and DTS.

In article 20050313161307.GB21955@wotan.suse.de you write:

According to http://www.dvddemystified.com/dvdfaq.html#3.6, the specs are as follows:
"Discs containing 525/60 (NTSC) video must use PCM or Dolby Digital on at least one track. Discs containing 625/50 (PAL/SECAM) video must use PCM or MPEG audio or Dolby Digital on at least one track. Additional tracks may be in any format."
So anything which is produced for more than one market will likely have AC3 as the smallest common denominator. (But recordings from DVB broadcast in PAL format which contain only MP2 audio make "valid" DVDs too. What do US broadcasters use?)

Hi all,
obviously we are now discussing 2 different problems. I want to summarize them here for clarification:
1. DVDs (at least in the PAL/SECAM area, as stated by Lucian Muresan) CAN contain MP2 audio tracks! Commercial DVDs mostly don't use this feature (instead they include AC3 2.0 Mono tracks, e.g. localized synchronisations of Star Trek: TNG DVD sets). If you create own DVDs from TV broadcasts (e.g. with vdrconvert), you normally get MP2 audio tracks (eventually as secondary tracks to a existing DD audio track if the station/VDR supports it). To my knowlegde the MP2 audio track is ALWAYS decoded by the DVD player. The must support it by the specs. The decoded PCM audio is obviously supported by any amplifier, even when transmitted via digital links (I hope this explains the problem for you, Werner). So this "problem" can be seen solved!
2. The original Mail asked for quiet another problem: If you want to record DD audio although you don't have DD equipment (at least connected to your vdr machine), you have to set UseDolbyDigital=1. If you do so, recordings will contain DD data it provided but VDR will replay MP2 audio over the analog outputs. The dvd plugin misunderstands the setting a bit by only providing the DD audio over the digital outputs but no audio over the analog outputs any more. The correct solution IMHO is to both provide DD audio over digital output AND decoded DD audio over analog output! So this is a feature request/bug report for the maintainer(s) of the dvd plugin (Hi Sven & Co!). THIS IS WHAT SHOULD BE DISCUSSED NOW!
