Difference between VTS_TTN number values

[setarip_old]

(Trying to learn a bit more about editing IFOs ;>} )

1) What does "VTS_TTN" refer to?

2) What is the difference between VTS_TTN=1 and VTS_TTN=3?

3) Why would one DVD's VIDEO_TS.IFO contain BOTH VTS_TTN=1 and VTS_TTN=3 pointing to the main video at the same starting sector?

A TTN is a title number within a VTS. It can be spread across many PGCs. It's just an ID#. In answer to Q3, because the video is the same (at least for cell 1).
