But I have checked 5 Blu-rays now without Any DVD HD running and the results regarding Surround or Stereo are exactly the same, so it does not matter if someone has ANy DVd HD running.

I've checked my last 5 Blu-rays, every one was copy protected.

In my opinion it very well matters if AnyDVD (or similar software for bypassing the copyright protection) is installed.

If you would read a few posts down what I wrote, there I corrected myself that with most Blu-Rays it only works when copy protection is removed

I've read it, I just wondered about the coincidence that although most Blu-rays are copy protected you picked five in a row which weren't.

I see no reason why a software shouldn't be able to check the DS flag in a DD 2.0 stream.

So thank you very much for starting the topic.

But yet one question: as I understand it the Dolby Surround flag can be set wrongly, meaning the flag is set while no additional information is coded into the audio stream, or vice versa.

If this is true, is it enough then to capture the flag?

Well,

Forget_The_Rest has confirmed some of my contributions also with his receiver, so I think we can be pretty sure here.

A thing that also speaks for the program is that for example on the BAtman Blu-Ray it clearly can distinguish between Stereo and Surround, as some of the DD 2.0 tracks are shown with Surround flag and one is shown without the Surround flag.

So I think we can be as sure as it can get

Why should BDInfo only pretend to check the Dolby Surround flag? To trick us here?

I've installed the free beta of DVDFab Passkey, and tested the first Blu-rays with DD 2.0 tracks. BDInfo reports tracks to be Dolby Surround which are currently format Stereo in the profile.

I didn't see Stereo and Surround on the same disc yet, but have no reason to doubt BDInfo's analysis.

That is what I think too, I trust the program, I haven't seen a betetr way so far to distinguish between Stereo and Surround

I've compared the results of BDInfo with two other tools, which differentiate between DD 2.0 Stereo and DD 2.0 Surround.

VLC 1.0.5
MediaInfo 0.7.32

Sadly, these don't seem to work for me either. VLC won't read Blu-Rays and MediaInfo doesn't display nearly as many fields for me. Most importantly, it leaves out Format Profile line. VLC seems to works for DVDs, at least.

Ace, you need to remove the copy protection, then every tool will work for you

Is there any shareware out there that will do this?  AnyDVD is not free.

I've been using BDInfo for a while now, and found it very useful
The source code is freely available, and I did download it and recompile it (even got some of my suggestions in the program ).
I started looking at making it do the same things for DVDs as it does for Blu-rays, but enthusiasm waned 

As for detecting "Surround" tracks, it does this by looking for the relevant bitstream flag being set in the audio tracks. Now, correctly encoded tracks should set the flags properly, but it has been known for them to be incorrectly coded. However, in this situation, our amplifier will also follow the bitstream flag, so you would have to know the flags are incorrect and manually override the amp (for example, a surround encoded track without the surround flag set).

Also, I got caught out recently by a Blu-ray that had many different "Playlists", and I took the runtime of the longest playlist listed. However, as it turned out, the longest playlist was not actually accessible through the menus, so the runtime was incorrect, and the shorter one was correct 

So I now try to double-check things in PowerDVD too.

MediaInfo has different viewing modes, yesterday was 'Sheet', this is how 'Tree' looks:

Alien, DVD, DD 2.0 Stereo and Surround, MediaInfo (Tree view)
(adds "Dolby Digital" if surround)
