Bypassing Paramount's "Previews/Main Menu" Selection Menu
Courtesy of 2C:cool::cool:L

Lately, I have encountered a lot of Paramount Region 1 DVDs that has a Previews or Main Menu option as a startup menu. Sort of like a aspect ratio menu with you selecting widescreen or fullscreen. I can't confirm for the other regions though but what I’ve noticed is that this clip always reside as a angle-menu in my VTS_02_0.VOB. Here’s what I have as viewed in IfoEdit in my VTS_02_0.IFO.
VTS overview:

Language Menu Unit 1: [English]
Menu 1: [Root-Menu] (entry PGC) (Programs: 0) (Cells: 0)
Menu 2: [Angle Menu] (entry PGC) (Programs: 1) (Cells: 1) (uses VOB-IDs: 1) Pre menu
Menu 3: [entry only] (Programs: 1) (Cells: 1) (uses VOB-IDs: 2)Post Menu
Note: If it's not the same layout in VTS_02_0.IFO, then search the other titlesets and you'll find one that fits the description above.

I want to get rid of this Preview/Main Menu startup screen so here’s I do.

Using IfoEdit, go to VTS_02_0.IFO / VTS_PGCI_UT / PGC-Menu_2 (Angle Menu) / PGC Command Table. Using the example below, double click on Number of Pre Commands and enter a “1”. Double click on Number of Post Commands and enter a “0”.
BEFORE:

PGC Command Table:
Number of Pre Commands 0
Number of Post Commands 1
Number of Cell Commands 0
Size of Command table in bytes 15
1.Post Command Set GPreg<0> mov (set-val)<1>(LinkPGCN) Link PGC 3

To refresh the screen, I use this personal trick. Click on “Show Reserved Values” checkbox and the you window will refresh. Scroll down to PGC Command Table to review your changes and this is what you’ll have. The Post command is now a Pre Command so that means the startup screen is now bypassed.
AFTER:

PGC Command Table:
Number of Pre Commands 1
Number of Post Commands 0
Number of Cell Commands 0
Size of Command table in bytes 15
1.Pre Command Set GPreg<0> mov (set-val)<1>(LinkPGCN) Link PGC 3

There’s also a post clip for this startup menu and it resides in the next PGC, which is PGC-Menu_3. Go to / VTS_PGCI_UT / PGC-Menu_3 / PGC Command Table. Do the same as what you did for PGC-Menu_2 and this is what you should have before and after.
BEFORE:

PGC Command Table:
Number of Pre Commands 0
Number of Post Commands 3
Number of Cell Commands 0
Size of Command table in bytes 31
1.Post Command Set GPreg<1> mov (set-val)<2>
2.Post Command If GPreg<0> == GPreg<1> then (JumpSS VMGM) Jump to VMG PGC: 22
3.Post Command (JumpSS VMGM) Jump to VMG PGC: 4

AFTER:

PGC Command Table:
Number of Pre Commands 3
Number of Post Commands 0
Number of Cell Commands 0
Size of Command table in bytes 31
1.Pre Command Set GPreg<1> mov (set-val)<2>
2.Pre Command If GPreg<0> == GPreg<1> then (JumpSS VMGM) Jump to VMG PGC: 22
3.Pre Command (JumpSS VMGM) Jump to VMG PGC: 4

Save VTS_02_0.IFO and BUP and play to test. You shouldn’t have your Preview/Main Menu pop up now.

hi 2cool!

thnx 4 all your efforts with your guides.

i was reading your post with great enthusiasm because i had exactly this issue with paramount's preview/main menu selection on STAR TREK NEMESIS. unfortunately, your description of the VTS overview does not match star trek's nemesis structure:

this is your description of how paramount's "VTS_02_0.IFO"'s usually are:
VTS overview:

Language Menu Unit 1: [English]
Menu 1: [Root-Menu] (entry PGC) (Programs: 0) (Cells: 0)
Menu 2: [Angle Menu] (entry PGC) (Programs: 1) (Cells: 1) (uses VOB-IDs: 1) Pre menu
Menu 3: [entry only] (Programs: 1) (Cells: 1) (uses VOB-IDs: 2)Post Menu


but paramount's stnemesis "VTS_02_0.IFO"'s structure differs:

VTS overview:

Menu attributes:
Video: MPEG-1 720x480 (NTSC) (NTSC 525/60) (4:3) (pan-scan & letterboxed)

Title Set (Movie) attributes:
Video: MPEG-2 720x480 (NTSC) (NTSC 525/60) (16:9) (pan-scan)
Audio 1: English (Dolby AC-3) 2ch 48Kbps DRC normal (ID: 0x80)

PGC_1 (program chain): [Title(TTN): 1] [00:00:21.00 / 30 fps] (Programs: 1) (Cells: 1) (uses VOB-IDs: 1)
[Ch 01] [Pg 01] [Cell 01] [V/C Id: 1/ 1] : time: 00:00:21.00 / 30 fps [Pos: 00:00:21.00] [Frames: 630]

PGC_2 (program chain): [Title(TTN): 2] [00:00:02.15 / 30 fps] (Programs: 1) (Cells: 1) (uses VOB-IDs: 2)
[Ch 01] [Pg 01] [Cell 01] [V/C Id: 2/ 1] : time: 00:00:02.15 / 30 fps [Pos: 00:00:02.15] [Frames: 75]

Menu Language Units: 1
Language Menu Unit 1: [English]

Language Menu Unit 1: [English]
Menu 1: [Root-Menu] (entry PGC) (Programs: 0) (Cells: 0)


here's an extract of the "VTSM_PGCI_UT" from its "VTS_02_0.IFO":

PGC Command Table:
[000000ec] Number of Pre Commands 1 [0001]
[000000ee] Number of Post Commands 0 [0000]
[000000f0] Number of Cell Commands 0 [0000]
[000000f2] Size of Command table in bytes 15 [000f]
[000000f4] 1.Pre Command (JumpSS VMGM) Jump to VMG PGC: 7 [30 06 00 07 00 c0 00 00 ]

There is no PGC Program Map

There is no Cell Playback Information Table

There is no Cell Position Information Table


i can confirm that pgc_1 and pgc_2 contain the pre and post menus.

correct me if i'm wrong: according to your guide, the preview/main menu selection would be skipped to jump directly into the main menu, right?

TIA

Hmmm...the Paramount menus I was talking about had you selecting Main Menu or Previews. Maybe it's in another VTS. Open up your DVD with DVD Shrink and preview. Tell me which VTS they are in to confirm if it's not in a menu.

What you posted and what you gave to me in your DVD dump does not sync up. You have an extra post command in your DVD dump and the Post command #s are not correct. Are you using PgcEdit v0.3.4?

VTST 2 / TTN 1 (0:21) Title 1

********** pre commands:
[51 00 00 80 00 00 00 00] 1 (SetSTN) Set Audio stream = 0
********** post commands:
[30 08 00 09 01 C0 00 00] 3 (CallSS) Call the VMGM PGC 9, resume cell 1 :confused:
[30 08 00 07 01 C0 00 00] 4 (CallSS) Call the VMGM PGC 7, resume cell 1
********** cell commands:
