I have a DVD where the first program/cell of a pgc is the special features menu. The other program/cells in the pgc are a series of graphics.

The special features menu has 3 buttons, 2 are linked to 2 titles and the third one is linked to the series of programs/cells containing the various graphics.

I want to be able to use the (root) menu button on my DVD Player when I am viewing one of the graphics so that I am returned to the special features menu (ie, the first program/cell of the PGC). I have tried modifying the DVD navigation in a number of ways in DVDReMake but without success. The resume function is always activated when I use the menu button no matter what I change.

It appears that when the root menu button is used while actually in a menu (rather than say, playing a title) 'resume'is always activated. I find that the same thing happens when I use the root menu button when in the chapters menu.

Is this resume function (when using the menu button while viewing a menu) an unchangeable feature of DVD design standards or can I do something to modify it?

Resume returns to the last played title. Look for the resume command by start tracing from the root menu. There will be some if statement with some R[x] that determines whether to resume or not.

You can add additional logics to go to the special features menu before this check for resume. In the special features menu, when the third button is pressed, set an unused register to 1 before branching to the graphics. Then in the menu pgc where the resume command resides, insert the if statement before the if check for resume to check if the unused register is set. If it is, then branch to the special features menu. If not, then execute the next if statement. Also, be sure to reset this unused register to 0 when you're in the last graphic menu.

If in doubt, post some screenshots of the associated commands (pre/post), or even better attach the menu shrinked VOB along with the IFOs (convert all menus to still, you can blank the middle graphic menus if you want to, disable the menu audio, and export modified files to some folder, zip this folder, and attach it here).

I have uploaded a zip to a filesharing site for your consideration. This contains the relevant files as per your instructions. I've reduced it as far as seems feasible without compromising navigation. It's about 2.5 mbs. The url for the file at the site is: http://www.mediafire.com/?hdygfdmbnim

Other than some minor illegal commands, seems like his problem has already been solved, i.e. to go to the special features menu when viewing one of the graphics. Don't know if he has modified already.

The TTN being 0 does not really affect playback, at least some has reported and I tested on my dvd players, but to be sure it's better to defined it to have TTN = 1.
