Menu change question: Ice Age

[mikewillnot]

I'm having difficulty making the menus on Ice Age play the way I want, and need a bit more educational help. Using IFOedit I stripped out the FBI warnings, etc, and the Standared format version of the movie; I now have a new file set that begins immediately with a Widescreen/Standard menu. Clicking on WS takes me to a cool animated root menu; all of the preceding seems to happen in Title 12, Ch 1. Hitting PLAY takes me to the main movie, Title 1 Ch 1.
I want to keep the cool animated intro to the main menu, but skip the widescreen/standard menu. I believe Title 12, the cool intro, is in VTS_1_0.* -- I just can't figure out how to skip that first WS/Std menu. Any tips would be grovelled for. Thanks. :confused:

Look in this sticky thread link for Ice Age Region 1. The version I had was a 2-disc set with movie on one disk and extras on the 2nd.

THANKS, 2COOL. 2 technical questions.
1. In step 8 from your cheat sheet (quoted below), could you explain how you "monitor the GPregs" and how you figured out the value 100/200 business? Or, direct me to some kind of a resource or reference?
2. Regarding the FBI warnings, etc, your method was to disable those menu items; I got similar results via MenuExtras, by stripping them out. Do you see a significant difference between the methods, or risks/tradeoffs?

-------------quoted from above-referenced thread-------------
8. In VTS_07_0.IFO / VMG Overview / Menu Language Unit 1, delete playback on the following.


Menu 6: [entry only] (Programs: 1) (Cells: 1) (uses VOB-IDs: 4)


Translation: Disables Aspect Ratio Selection Menu before the main menu.

Details: Usually, I monitor the GPregs to see which GPreg holds the value for your widescreen and fullscreen version. GPreg<9> was our culprit. A value of 100 would give your widescreen and a value of 200 would give you fullscreen. In this DVD, we didn’t need to set/force GPreg<9> to 100 as it was 100 to begin with.
