There are more disclaimers to Kill Playback.
If you have any of these present in your Pre Commands after Kill Playback, the Title's cell(s) will still play.

Killng Playback
Folks,
I am not convinced that Killing Playback (or as jsoto/2COOL say, changing post in pre commands) is wholly a good thing. As jeannl has pointed out - in several of her posts - if playback is killed, the GP Registers may not be correct. This would be especially true if BREAKs are converted to GOTOs. I have had this experience recently - I blanked a lotta rubbish from the VMGM domain using VOBBlanker. The menu came up OK but the DVD didn't play. Tried again, without having pre commands turned into posts and it worked beautifully. Of course, the (now blank) VOBs played (for 1/2 second), but big deal. I think this is the big feature of VOBBlanker - the ability to blank cells, without affecting either the disk's structure or GP registers. Maybe VOBBlanker should have it disabled by default. Comments?

Each DVD has its own tricks...
I agree there are some cases where the final DVD does not work (or does not work properly), but I'm still convinced the defaults in VobBlanker are the right ones (the most common). jsoto

@Blutach,
Quote:
However, what vobblanker and pgcedit do is different. They convert the postcommands into precommands, and change breaks to goto. The result is that in the absence of cell commands, the pgc does exactly what it did before: the same commands are executed in the same order. The difference is the PGC "exits" (goes where it normally would) before any video is played back. I think the whole idea is due to 2COOL, kudos to him, that's very clever . Now, if there are cell commands, that's different because these won't be executed (because no playback -> no cell command). Also, if there are link commands in the precommands, playback might actually not be killed (but that's not what's happening in your case). However, vobblanker is smart about cell commands and it gives you a choice to kill or not kill if there are cell commands. In your case, I would definitely check whether the PGC that you killed had cell commands. If not, this would mean that there's something broken with vobblanker's kill playback. Also, I would definitely try to do the same kill playback using pgcedit. If that works, then there's a problem in vobblanker. 2COOL, can you confirm that? If there are no postcommands, killed or not killed playback should leave GPRMS, SPRMS in exactly the same state, right? Jean P.S. I'm a he, jean is a male name where I come from |

Cell commands
My apologies Jean - I didn't suspect a French name (I just saw California, ).
I will have to have a look at the burned disk and see if there are cell commands. But I guess that is the point - if no BREAK, then no cell commands can execute, possibly screwing up the GPRMs.

@jsoto and jeanl
I've looked at the cell commands in VMGM and each cell only has a LinkTail PGC, which simply links to the Post commands. @jsoto - Are the Post Commands still present under VOBBlanker (a la PGCEdit?) If so, I'm not sure what went wrong. Regards

@blutach,
You should definitely get to the bottom of that. You're the second user who's encountered a problem of this nature (I'm trying to find the post), and I'm pretty sure things should definitely be OK in the case you describe. I'm pretty sure vobblanker leaves the postcommand there anyway (but in any case that's only useful if there's a link in the precommands and playback isn't actually killed). Here's what you could do: - Check that indeed playback is broken, narrow that down to 1 PGC being killed and breaking the DVD. - Then post back the precommand/postcommand/cellcommand from pgcedit in the original PGC and the killed PGC. We should be able to figure out what went wrong! I know it's a bit of work (including burning if playback only breaks on your standalone) but it's worth it . Jeanl |

@jsoto
The Posts changing into Pre commands is one thing, but if, for some reason, the cell plays and there are no post commands left, then problems may occur. In PGCEdit, r0lZ essentially COPIES the post commands to the pre command section leaving the post commands untouched (He also converts BREAKs to GOTOs). That is, the post commands are still there as post commands (even though they may never be executed) after the PGCEdit Kill Playback routine. I have never had a problem with this idea. But as 2COOL and others have pointed out, the cell may still execute and if there are no post commands to execute, then we may have an error situation. I will look at the disk again and report back. Regards

@jeanl
(Tongue in cheek) If we had a nice trace function in PGCEdit, it would be very easy to track down @r0lZ I know you're working on this, so, please don't take offence. I just mention it because I know Jean has wanted this for some time

BTW, you may not kill playback on a menu with buttons. Have you checked that?
