New Dvds with 99 Title tracks, which one is the correct track?

Solution 1:

I came across this when I was back-up some tv-shows to Apple TV. As a solution I use VLC to figure out what the right chapter number is.

Just start the DVD in VLC and start the movie/select TV show. When it runs you can check under Playback>Chapter what the corresponding chapter# is

Solution 2:

ARCCOS is the protection schema's name. 99 is the maximum number of tracks that can be burnt to a DVD, but I don't know of a programmatic way to select the correct one or if there are web sites that perhaps contain this information. For my Star Trek disk, the "playable" title is #21. Same as yours? If so, then maybe an online DVD database containing playable title numbers might be in order. It would be easy to code, and you could make millions!!! LOL.

Probably not, though. Only thing you can do now is just play in your player and wait until the movie starts, then read which track it's playing.
