PGCEdit Question

[billynews]

Hi,

I need some help with PGCEdit - if it's the right tool for my problem. If not, you may tell me the proper one.

I've tried to shrink a TV-Show DVD9 to DVD5 with DVDFab but the result does not play Episode 1 (of 4) from the
Episode Menu. Instead the player jumps back to the Episode Menu.
I think my problem is not related to DVDFab but rather to the way the original disc was authored. So I thought PGCEdit
could be the tool to fix the shrinked DVD.

If I play the original disc I'm getting first the Main Menu which lets me select e.g. Episode 1. Then I get the Episode Menu
and if I select "Play Episode" for the first time the player first plays 2 Warnings (FBI, Interviews & Commentaries) and then
the Episode. (Usually this warnings will be played before getting to the Main Menu - but on this disc they will be played after
selecting any Episode for the first time)
If I try to play Episode 1 from the shrinked disc, the player just jumps back to the Main Menu instead of playing the Episode.
Even if I keep both warnings in DVDFab the player jumps back to the Menu.

I found out so far:

1. VTS for FBI Warning is 22 and has the following commands:

I hope some experts can tell me how to change these commands to get
a running DVD.

[billynews]

found a workaround - CloneDVD2 creates a running disc.

Thx, and please close this question.

[Baldrick]

Thanks for posting your solution. But we don't have to close this one...maybe someone knows the answer for the pgcedit question.

[billynews]

well, if someone knows the answer I would like to know it as well.
I spend some time on trying to fix it with PGCEdit, but wasn't successfull.
I have planned to compare both results with PGCEdit - I hope to find the difference(s).
If yes, I will post them here.

So, CloneDVD2 didn't change pre- and post commands for this titles.
And there's another difference: DVDFab has removed VTS28 to VTS33.

********** cell commands:

As you can see, it has replaced the conditional Break and all conditional LinkPGN with Goto line 17.
The Break command tells the player to stop parsing the pre-commands and to play the video at the beginning.
The LinkPGN are similar commands, but the playback begins at a specific Program. (Usually, Program is equivalent to Chapter.)
Line 17 does nothing, and line 18 returns to the menu.
(BTW, it has also removed the original post-command, and that's an error IMO.)

So, obviously, it has changed the pre-commands to make that PGC unplayable, and return to the menu immediately.
As you say in your last post, it has also removed some VTS, and probably the video of the episode, so even if you restore the original pre-commands, the PGC will probably just play a black still frame.

Now the question is: is it really a DVDFab bug, or did you told it to remove it by mistake?
