I've been looking at available tools for analysing Blu-Ray discs, and have had a look at BDInfo, which is currently v0.5.1.
This looks like a great tool, which displays pretty much everything you could want to know about the video/audio streams in the various playlists on the disc 
However, I found a problem: it automatically sorts all the streams, so that they don't get lists as they are encoded on the disc 
This is particularly relevant to Audio Streams, as the rules says

Quote:
List audio tracks in the order in which they are encoded on the disc, determined via your DVD player or DVD-ROM drive.

and BDInfo does not necessarily display the tracks in the encoded order 

I've taken the source code for BDInfo (freely available), and located the offending line in TSPlaylistFile.cs

Quote:
AudioStreams.Sort(CompareAudioStreams);
foreach (TSStream stream in AudioStreams)

which I've modified to

Quote:
if (BDInfoSettings.SortAudioStreams)
{
    AudioStreams.Sort(CompareAudioStreams);
}
foreach (TSStream stream in AudioStreams)

using a new global option "SortAudioStreams", so Audio sorting can be toggled on/off.
Anyone with a suitable compiler can also change the sorting option by simply commenting out the call to the Sort function

Quote:
//AudioStreams.Sort(CompareAudioStreams);
foreach (TSStream stream in AudioStreams)

I'll see if I can talk to the developers, and see if they will implement such an option for "purists" such as us 

In the meantime, take care using this tool to correctly order the Audio Tracks, as it will probably be listing them incorrectly.

Quoting Katatonia:

I'm pretty sure that PowerDVD 8 Ultra displays the audio tracks in the correct encoded order for BR discs when playing, but I haven't used it enough to be certain yet.

As does the version 7 iterations that handle BD/HD-DVD.

When i directly command my PS3 to change Audio tracks (not using the menus, simply commanding it to cycle thru the tracks) they match the order PowerDVD gets.

Quoting Katatonia:

... I don't know why Cyberlink didn't just leave HD-DVD support on version 8.

...and I still prefer the version 5 interface better than either of those versions!

My guess is that they would have to pay a fee to HDDVD (Toshiba?) for the right to play HDDVD disks.

Just to update ...
I gave some feedback to the developer, and he has incorporated some of my suggestions in to the lastest build 
So v0.5.2 now has an option to keep the original stream ordering, which you will need to turn on once in the settings.
The Rescan button was a suggestion, because I am lazy    he's augmented it so that it remembers the path between sessions too ... sweeet 

If only there was such a detailed tool for DVD's too
