Are the files you uploaded the original, before doing Jump to PGC procedure? Looks like it.

**notec** · 30 Mar 2007, 02:54 PM

No these are the "after" the jump files...

Looks right. How about Title 2?

The behaviour of the DVD players after STOP is complex.

When you press STOP during the playback of a Title, and then Play, the player should resume to the same Title, at the interruption point. In other words, the navigation should continue normally, exactly like after a pause. You can even turn the player off and on after STOP. The intention is to allow the user to resume to the stop point if he leave the DVD in the player.

On the other hand, when you press STOP during the playback of a Menu, or when you press STOP twice during the playback of any Title, and then Play, the player should execute the pre-commands of Title 1. However, in this case, all GPRMs are reset to 0 before executing Title 1. This means that the navigation can be redirected to any point of the DVD, depending of the pre-commands of Title 1.

To force the playback to return to the FP-PGC, you have to use a free GPRM. In the examples below, I assume GPRM 15 is unused.
In the FP-PGC, init GPRM 15 to any value different than 0:

Code:

VMG , First-Play PGC  - Chapters: n/a,  Programs: n/a,  Cells: n/a 

********** pre commands:
   1  Set gprm(15) =(mov) 1 
   2  ...

In Title 1, test if GPRM 15 has the value 0. This means that Title 1 is entered directly after STOP. In this case, restarts the DVD completely from the beginning by jumping to the FP-PGC:

Code:

VTST 1 , 1   TTN 1  (1:47:35)  Title 1 - Chapters: 21,  Programs: 21,  Cells: 21

********** pre commands:
   1  if ( gprm(15) != 0 ) then { Goto line 3 } 
   2  (CallSS) Call the First Play PGC, resume cell 1 
   3  NOP 
   4  ...

Of course, if you prefer to play directly Title 1, you can use:

Code:

VTST 1 , 1   TTN 1  (1:47:35)  Title 1 - Chapters: 21,  Programs: 21,  Cells: 21

********** pre commands:
   1  if ( gprm(15) == 0 ) then { Break } 
   2  ...

Note that you can theoretically also jump to any Title after STOP (or STOP twice.) You have to type the number of the title, and then press Play. You might have to modify all Titles if you want to control exactly what happens after STOP.

It is always possible to force the player to restarts completely the DVD from the FP-PGC by opening and closing the tray.

Of course, that's only theoretical. Many players haven't implemented this feature correctly. My KISS, for example, restarts always the DVD from the FP-PGC.

@r0lz

I think I know what you're getting at and will experiment when I get home tonight...

**blutach** · 31 Mar 2007, 05:56 AM

My players with this resume after stop feature all resume at the resume point. What player do you have notec? The implementation of J2PGC looks fine BTW.

Regards

**notec** · 31 Mar 2007, 06:25 AM

I use a Sony DVP-NS50P. It typically plays *everything* I put in it without problems. I put it in my older Panasonic DMR and the behavior was exactly the same as on the Sony.

**blutach** · 31 Mar 2007, 06:33 AM

I'll try this on my SONYs again.

EDIT: Pressing Stop in a title is the same as r0lZ has said on my 2 SONYs.

Regards

**notec** · 31 Mar 2007, 11:26 AM

CORRECTION: It's when you press STOP twice. That's when I plays the jumped previews when pressing play again. Sorry for the incorrect report.

**blutach** · 31 Mar 2007, 12:11 PM

r0lZ has said that in this case, the spec is to start by executing a jump to title 1. Your movie is in VTS 2 and is VMG title 2.

I reckon what will happen is that title 1 will take us all over the place and finally get you to the menu.

Obviously, to stop this behaviour, you need to open/close. Or consider blanking the offending material with PgcEdit, VobBlanker, DVD Remake Pro or even do a movie and menus rip in RipIt4Me.

If you wish, post your IFOs (as a complete set) and we will verify.

**blutach** · 31 Mar 2007, 03:02 PM

Aaah yes, my mistake. That's just the title you resume to if you press RSM during the menu.

Going blind here.
