What if menus are VTST instead of VTSM

[cipputi_01]

Dear all

I need help about some special cases that PgcEdit is, apparently, unable to properly manipulate.

After the decryption, when scanned with PgcEdit in order to program the language and subtitles as described in the guide written by Jeanl, some of my commercial DVDs show that, instead of having normal menus (VTSM or VMGM files) with the associated buttons, have VTST files with any button associated to the shown selection fields. In such cases, PgcEdit don’t stop (as usually) the “Trace mode” scanning showing a menu and, if you visualize in “Preview PGC” mode the VTST file related to the “pseudo menu”, no choice can be made.
More over, when the program execution reaches the “pseudo menu” area, it usually remains in a loop (see an example at the end of this message where the titleset VTST 1 , 4 TTN 4 is the “pseudo menu”), evidently waiting for an input that (may be) through PgcEdit cannot be given.

At this point, the only solution that I’ve found to make my copies (a merely decrypted copy doesn’t work) is to jump from the First play PGC directly to the film and loose all the menu possibilities.
I’ve found no mention in the Doom 9 domain about these cases. May be you can better address my search?

Thank you for your answer

What version of PgcEdit are you using? PgcEdit v5 and above detects Buttons Over Video (which are buttons in VTST) and works the same way as if they were in VTSM.

To detect the BOVs (that's the way these special buttons in title domains are named), you have to scan the title's VOBs for BOVs. By default, PgcEdit 0.5+ scans the VOBs when the DVD is opened. If you turned that option off, you will have to select the menu File -> Find BOVs. When the scan is complete, you will see the number of buttons also for the title PGCs, in the PGC selector.
Now, the Trace function will be able to show the buttons, and request your inputs.

not quite sure, what cipputi_01 is after, but somehow i got the feeling that he'd like to jump directly from 1st play PGC to the menu and skip all the other stuff that's normally in between. and that target menu is in VTST.

isn't it so that such a menu must be a title and then he just have to set the registers as they're set by the orginal stuff and jump to that title?

Yes, the method to jump straight to the menu (jeanl's method, or 2COOL's Jump2PGC) should work also if the menu is in the title domain. You have to use another jump command, but the rest should be identical.
