FAQ about DVD structure ?

[rduck]

Hi,

Does anyone know whether a FAQ or similar exists about the structure of a DVD (didn't know where else to ask this question) ?

Right now I'm sitting with a DVD in DvdReMake Pro, and I'm looking at the structucture of the DVD with Video Title Sets, PGCs (Program chains ?), VMG titles etc....
When checking the menu of the particulat disc, I have a PGC 1 (root menu), PGC 2 and a PGC 3 (PGC 3 aparently wityhout any picture). In PGC 1 and PGC 2 there are 2 programs (or cells ?), and the menu has some PRE/POST commands, eg.

if (R[7]==1) Resume
if (R[15]!=2) Goto line 14
Jump title 2 chapter 1

and the buttons on the menu have different commands, e.g.

R[15]=4, Link TailPGC
or
Link Program 1

What I'm looking for is some kind of description of all the concepts, commands etc - maybe by "disassembling" a DVD, and go into details on exactly happens during playback etc of the disc...

The reason for my question id that I'd like to combine a 2-sided DVD (having a number of episodes from a TV series on each side) on one DVD - and try to merge some of the menu-stuff....

Anyone ?

Hi,

Okay, I think I'm beginning to understand some things about the structure now. Quite interessting, actually ;-)

One question remain, though (regarding my little "project").. I have to add a new button to an existing menu. Doing this in DvdReMake is no problem - but I wonder how I can get the button highlighted (another color), when the "cursor" is placed on that button... Any recommendation on what program can be used for editing the bitmap file (it's a stilll-picture in the menu), sp I can get the button highlighted the correct way ?
