How change where cursor returns on menu?

That was so cool! Watching the step trace, I mean. I totally could follow what was going on after having read your excellent explanation beforehand. That really helped me to follow the algorithm as it played through.

I totally see what you're talking about by changing R[8] from 1 to 4, that it would make the if statement "if (R[8] > 3) Link PGC 2" true because now 4 is greater than 3 then do Link PGC 2.

But to be honest, that's isn't what I'd like to have happen. I don't want Page 2 of Special Features to automatically open upon the completion of playing Featurette #3. What I'd like is for the cursor to just be sitting on More and wait. What do we need to add in the code? Perhaps something like this?

Current Pre Command code:

Line | Command

1 if (R[15]==0) goto line 13
2 if (R[8]>3) Link PGC 2
3 if (R[8]==1) goto line 7
4 if (R[8]==2) goto line 9
5 if (R[8]==3) goto line 11
6 Link Cell 1 (highlight button 1)
7 R[8] = 0
8 Link Cell 1 (highlight button 1)
9 R[8] = 0
10 Link Cell 1 (highlight button 2)
11 R[8] = 0
12 Link Cell 1 (highlight button 3)
13 Jump VTS Title 9

After adding some lines:

Line | Command

1 if (R[15]==0) goto line 16
2 if (R[8]>3) Link PGC 2
3 if (R[8]==1) goto line 8
4 if (R[8]==2) goto line 10
5 if (R[8]==3) goto line 12
6 if (R[8]==4) goto line 14
7 Link Cell 1 (highlight button 1)
8 R[8] = 0
9 Link Cell 1 (highlight button 1)
10 R[8] = 0
11 Link Cell 1 (highlight button 2)
12 R[8] = 0
13 Link Cell 1 (highlight button 3)
14 R[8] = 0
15 Link Cell 1 (highlight button 4)
16 Jump VTS Title 9

But I foresee a problem. The if statement "if (R[8] > 3) Link PGC 2" is still true since R[8] is now equal to 4 that was changed in PGC6 (title 6). It will still do the operation Link PGC 2. How can this be fixed so that it doesn't do that branch off to Link PGC 2?

By the way, what does the Link Cell 1 command do in "Link Cell 1 (highlight button 3)"?
I think I get what "(highlight button 3)" does. It puts the cursor on button 3 in this case, correct?

Okay, I implemented the changes and it appears to be working as I want it to. The cursor is returning and sitting on More. I don't see any side effects happening.

Now, I decided to try my hand at cleaning up the code and deleting the unnecessary, unreferenced PGCs and whatnot in the tree structure.

Some questions, toaddub...

1. Why did they put in two of the same block (7.03 Mb) of the Warner Bros. logo and not simply reference and make a call to, a single block twice? That seems redundant to do, no? Is there a good reason that they did it the way they did?

1a. And why does the Warner Bros. logo block appear only once in the VTS2/Program Chains/Domain Content pane (the "filmstrip" going horizontally), but appears twice on the tree of VTS2/Program Chains? I'm confused. Is that Warner Bros. logo block taking only 7.03 Mb or twice that 14.06 Mb of the disc space?

1b. What would happen if I deleted one? Could it be tailored to still work as it does now? Or would that screw everything up?

2. There are two PCGs (PGC3 & PGC4)in VTS2/Program Chains, each of only 0/01 Mb. I believe these are the two blocks I hit "Hide block" on since they're still there (in the "filmstrip" going horizontally), when I click on VTS2/Program Chains in the tree.

When I delete them with "Delete PGC", some lines go red screaming at me that they're being referenced from here and there in the algorithm. When I go into VTS2/Titles to delete the referenced lines, (e.g. Title 4 (vmg title 9)), it screws things up even more.

I guess what I'm asking is if there's an easy or simply way to delete dead Program Chain PGCs and Menu PGCs that have been hidden, and not screw up the rest of the algorithm.

Both PGCs 2&9 have the same Warner Bros. logo because they share the same cell/block, as shown in the Domain Content view. Though they have the same content, they may have different purpose as shown with different commands in each.

When you delete a PGC, you have to adjust the navigation accordingly so it won't break. When you see red line(s), you have to fix it till the error goes away. I often trace ahead so I know where to reroute/adjust the navigation before deleting items. Use of Notepad to make notes would be helpful.

Since you're not familiar with VM commands yet, it's not time to delete PGCs. Besides, the space saving is very negligible. There is no easy way to delete hidden PGCs. If the item is unreferenced, deleting it would be no problem. But if it is hidden and still called, you will have to fix the navigation if you delete it.

To answer your first question.
There is sometime two PGC with same thing, like logo, to go to from different place. In most cases it is to make navigation easier as far as commands go.
You will find that sometime there are two menus for the same reason, instead of using cell they insert other PGC.
As long as it all fit on DVD9 it is OK.
It is like any other programing, sometime it is very efficient, sometime there is lots of stuff which can be done better.

To your last paragraph.
It is not always that simple to only delete red commands as they can reference other PGC.
If you want to delete stuff, you are better off to start your own navigation, because there is lots of registry values that can be deleted also.
But like toaddub say, PGC with commands only, will not increase file size significantly. It will only show when DVD is played, as it will take longer to go from one section to other. Sometime it take quite a while to jump from one menu to other, just because too many commands in between to be processed by the player.

Yes, I think it is in the wish list. PgcEdit has sorta similar feature, where you can jump to any PGC upon DVD insert (from PGC menu), and PgcEdit reroutes the commands for you. When done, you can use its macro Info -> Find Uncalled PGCs and delete them - just to clean it up.

In fact, from your merged test file (the first uploaded one), PgcEdit finds there are many uncalled PGCs that you can use as a reference and delete them manually in DvdReMake.

PgcEdit is good, but I still find it hard to navigate in. ReMake is definitely much more "user friendly" and what I like on it, that you see the structure.
Commands are also much easier to understand, even that they do not follow official format, may be that is why.
I usualy delete all the stuff I do not want and start my own navigation.
That way I do not have to worry about somebody else line of thought.

Thanks, guys. That PgcEdit sounds intriguing for that feature to find and then delete uncalled PGCs. I may play with it some time when I have more free time.

I too like DRMP's user-friendliness and that's a big reason I use it. I really do hope this "cleanup" feature does make it from wish-list to actuality in a future version. It would be a real enhancement to an already great software program.
