Can't Skip Previews on Back-up

[trubeliever]

I made a 1:1 copy of "The Break-up," but for some reason I can't skip or stop (pressing the stop button) the previews before the main menu. The strange thing is that on the original disc the previews are skippable and even mention this at the beginning of the disc (i.e. "You may press the main menu key at anytime during the previews").

I used the default settings of RipIt4Me and ImgBurn. Should I be checkmarking a certain box in Settings?

Try these tips:

1. In DVD Decrypter's settings, in the File Mode tab, turn on Remove IFO PUOs.
2. While screening the previews, press Next on your remote.
3. If all else fails, load the rip in PgcEdit and use DVD --> Enable Navigation Buttons (as shown below). Save (Ctrl-S) and burn.

Thx blutach for responding,

Removing the IFO PUOs worked perfectly, but I also have another question: do I need to have the "Remove IFO Structure Protection" box checked when doing 1:1 copies? I was looking at cynthia's DVD Decrypter user guide and it mentioned that this was mainly for removing the first blank five minutes of Sony ARccOs DVDs, but wasn't necessary to remove for 1:1 copies. Just wanted clarification. Thanks again.

You can have it enabled or disabled, as RipIt4Me will disable it during the run in both file mode and ISO mode.

Another solution is to jump immediatly to the desired pgc, without blanking or deleting anything.

This cool solution lets you start your dvd whereever you want with the right language and subtitle settings.

I found out that blanking cells or pgc's can give problems on my standalone Philips DVP5960, even when the dvd played fine in Media Player Classic. Blanking means the video is replaced by a dummy but all the precommands and postcommands are executed. So instead of a warning logo or a trailer from another movie you would see a black screen for a second. Don't know why but my Philips doesn't seem to like this technique and sometimes stops playback.

I also watch out with removing PUO's. Why? Suppose there is a pgc with 3 cells. The first cell is supposed to play before the main movie, and cell 2 and 3 are supposed to trail the main movie. Pressing 'next' during the playback of cell 1 would take you to cell 2, and finally cell 3. So you come to the end of the dvd without seeing the main movie, because the navigation would be screwed up. That's why I sometimes ADD puo's

Good points Calimari. All my menu PGCs are 192. This is especially true for Chapter menus authored in the one PGC.

Don't forget about RipIt4Me's Jump to Menu option, which is as technically correct as PgcEdit's.

To get around your finicky playback issues, blanking can also do a Kill Playback (no 0.4 second of blackness). Simply add the post commands to the precommands. PgcEdit does this easily, as does VobBlanker.

Sounds interesting. I never tried it but I sure will.

Yes, I know and that's what I usually do. But recently I did 'Calendar Girls' R2, which has 3 trailers in the beginning. Each trailer is a cell in that pgc. I killed playback of the entire pgc and my Philips standalone stopped playback at that point. Only the standalone had problems, MPC on pc played just fine what I had produced.
So I compared the result to the untouched version (RipIt4Me rip) and as you said, the only difference was that the postcommands were added to the precommands. Theoretical, this should work fine, though my standalone didn't like it, still don't know why (could it be a time issue?). Once I blanked all 3 cells in the pgc but did not kill playback (what PgcEdit suggested), I managed to play the disc on the Philips.

Generally, I like the idea to jump to the desired pgc with all GPRM's set correct, rather than run through all those blanked or playback-killed pgc's.
In case of Calendar Girls, I went through the entire navigation and found out that the opening trailers were never played again. Finally I did kill the playback of that entire pgc, but as the standalone skips them now, the disc plays fine.

I just noticed that the Jump-to-pgc manual is yours
Good work!

Blutah, I tried 'Jump to menu' in RipIt4Me with 'Calendar Girls' R2 rental version. This takes me to the first menu on the disc: the disc-language selector. Then I have to watch those annoying trailers again, to arrive where I want to: the main menu.
Seems like RipIt4Me's Jump To Menu is navigating to the first menu on the disc?

[r0lZ]

That's right. It has no way to know which menu you want to use, and assumes it's the first one.
The PgcEdit method let you choose exactly what you want.

I've heard many times that blanking a PGC is unsafe for several standalone players. However, when the playback is killed (post commands moved to pre), the cells are never played, and it should work fine on all players.

Another cause of problems might be that there are some Link pre-commands that jump directly to a specific cell. But it's probably not your case, as the DVD plays fine with MPC. Anyway, PgcEdit refuse to kill playback of such PGCs. Not sure if the other programs do the same thing, as I use always PgcEdit for this job.


BTW, I agree also with your PUOs method. It is generally unsafe to remove them all. Personally, I remove them from the VOB files, as it is difficult to remove them manually, but I leave them in the IFOs, and modify them to suit my needs.

Perhaps the author of RipIt4Me could think of a way to take care of PUOs that doesn`t have the risk to mess the dvd, and something to choose to what menu exactly you want to jump to ...
If of course could be done in a simplified way that matches the whole spirit of the program ... We`ll see ...

[r0lZ]

IMO, guessing which PUOs must be kept is not easy, as it's essentially a matter of taste of the user, and the utility of a specific PUO depends of the PGC. And don't forget that the PUO are generally removed by DVD Decrypter during the ripping phase anyway.

A GUI to let the user choose which menu to jump to is not easy to do for the author, I'm affraid, as RipIt4Me has no preview to display it.

That's what I also had in mind, but it seems to turn out different this time.
I did the Kill Playback in PgcEdit and it didn't refuse like it does when you try to kill a pgc with commands that link or jump outside the pgc.

These are the commands before and after killing playback of that pgc:

Before:

********** pre commands:
1 Set gprm(1) =(mov) 0
2 if ( gprm(3) == 1 ) then { Set gprm(1) =(mov) 1 }
3 if ( gprm(3) == 2 ) then { Set gprm(1) =(mov) 2 }
4 (SetSTN) Set Audio stream = gprm(1)
5 Set gprm(13) =(mov) 0
6 if ( gprm(3) == 3 ) then { Set gprm(13) =(mov) 64 }
7 if ( gprm(3) == 4 ) then { Set gprm(13) =(mov) 65 }
8 if ( gprm(3) == 5 ) then { Set gprm(13) =(mov) 66 }
9 if ( gprm(3) == 6 ) then { Set gprm(13) =(mov) 67 }
10 if ( gprm(3) == 9 ) then { Set gprm(13) =(mov) 68 }
11 (SetSTN) Set Sub-picture stream = gprm(13)
********** post commands:
1 LinkPGCN PGC 2
********** cell commands:
1 LinkTailPGC


After:

********** pre commands:
1 Set gprm(1) =(mov) 0
2 if ( gprm(3) == 1 ) then { Set gprm(1) =(mov) 1 }
3 if ( gprm(3) == 2 ) then { Set gprm(1) =(mov) 2 }
4 (SetSTN) Set Audio stream = gprm(1)
5 Set gprm(13) =(mov) 0
6 if ( gprm(3) == 3 ) then { Set gprm(13) =(mov) 64 }
7 if ( gprm(3) == 4 ) then { Set gprm(13) =(mov) 65 }
8 if ( gprm(3) == 5 ) then { Set gprm(13) =(mov) 66 }
9 if ( gprm(3) == 6 ) then { Set gprm(13) =(mov) 67 }
10 if ( gprm(3) == 9 ) then { Set gprm(13) =(mov) 68 }
11 (SetSTN) Set Sub-picture stream = gprm(13)
12 NOP
13 LinkPGCN PGC 2
14 NOP
15 LinkPGCN PGC 2
********** post commands:
1 LinkPGCN PGC 2
********** cell commands:
1 LinkTailPGC


As you can see, the postcommand is added to the precommand.
Is it normal it is added twice? And does it always has a NOP in front?

It is generally unsafe to remove them all. Personally, I remove them from the VOB files, as it is difficult to remove them manually, but I leave them in the IFOs, and modify them to suit my needs.

You do this in DVD Decrypter in the File Mode Settings?

And don't forget that the PUO are generally removed by DVD Decrypter during the ripping phase anyway.

Does RipIt4Me overrides DVDD PUO-settings?

@ rOIZ

I thought so , too , that is a little difficult .... But, who knows ....

And don't forget that the PUO are generally removed by DVD Decrypter during the ripping phase anyway.

That is something a little strange for me and we discussed it again in another thread with Blutach. At least in my computer last time I checked, when RipIt4Me calls DvdDecrypter just before the rip when you can see the preferences, in file mode both options for removing IFO and VOB PUOs are unchecked. In the future I`ll try checking the ifo puo before the rip by myself.

[r0lZ]

As you can see, the postcommand is added to the precommand.
Is it normal it is added twice? And does it always has a NOP in front?

That's correct. This PGC should be played without problem.

No, the post-command should be added only once. Did you kill the PGC 2 times? Anyway, it doesn't hurt.

And yes, the NOP is always added (unless there is no room for it, if the 128 commands limit is reached.) The NOP is the target for the Break pre-commands changed to Gotos.

You do this in DVD Decrypter in the File Mode Settings?

Yes. But you can also remove the VOB PUOs of the VOBs with the PUO plugin for PgcEdit.

Does RipIt4Me overrides DVDD PUO-settings?

I don't know, but it is probable that it tries to analyse the files as they are on the original DVD. But IMO it should not overwrite the user setting when ripping the final files.

Seems Vaios has just replied to the question.

[Calimari]

Did you kill the PGC 2 times?

No, I double-checked, I only killed it once.

Anyway, thanks for the great info.

For those who read this and who are unexperienced with PUO- stuff:
DVDShrink also removes them.
You can find this setting in 'Preferences- Output files'.
Watch out what you're doiing with it, when you decide to transcode with DVDShrink. As rOLZ said, it isn't always the best solution te remove them, as the user can screw up dvd navigation manually when having too mutch freedom
