Audio track numbering in DGIndex

[berrinam]

In DGIndex, are the audio tracks always set to count from one up, for any type of MPEG2-compatible audio? What I mean is, if there is one audio track, will it always be labelled Track 1, and if there are two audio tracks, will they be Tracks 1 and 2, and so on?

For program streams, the audio stream ID is used to determine the track number:

0x1c0 (stream 0) -> Track 1
0x1c1 (stream 1) -> Track 2
etc.

For transport streams, only one audio PID can be selected, so it is always assigned to Track 1.

I cannot guarantee that DVD makers start populating tracks with stream 0, but I haven't seen a counterexample. Probably 'mpucoder' would know more about that I do.

Thanks for your response.

Is there any way to make a mapping between the audio Stream ID and the substream IDs?
E.g. a DVD that has two AC3 tracks and a DTS track with substream IDs 0x81, 0x82 and 0x88, DGIndex names the DTS one (0x88) xyz_T01...dts, the first AC3 one xyz_T02...ac3.
Ripping tools generally list the substream ID... is there any way to make a 1:1 match that works in call cases?

I don't know what you mean by "substream ID".

Please tell me how to see the "substream ID" using, say, DVDDecrypter.
