help with post commands please

[mmoalem]

hi there all - not sure if this is basic or advanced question but i'll try this first... I need to loop the pgcs in my dvd so when they reach the end they start again but i also want them to progress to the next pgc when pressing next chapter. I have authored it in reeldvd and found some info on how to change the post commands (which is not possible in reeldvd) with ifoedit but that info didnot detail what i should write into ifoedit (i.e. the right syntax)...
any help will be greatly appriciated...)
cheers

Open your ifo. Go to VTS_PGCITY and click on your last PGC (the one you want to start looping after). Go to the PGC command table (scroll down in bottom window). Choose add post command. Then right mouse click on this comamnd and choose edit. Jump to PGC and set the PGC you want to start.

thanks for the advice - will try it when i get back home... the question is would i still be able to press next chapter to get to the next pgc?

I this is already working now: yes.

You're only gonna add a post command to jump back to the first PGC to the last PGC. The rest you can leave as it already is.

hi there again - i think i was not clear enough about what i was trying to achive... lets say the dvd is made of 5 PGCs. eache a minute long, each is one chapter. I want ALL of them to loop - i.e. play untli i press next chapter on the remote which will take me to the next PGC which will in turn play in a loop until i press next again...
The DVD is of videos to be projected in a live gig, each corresponds to one track and play continuasly until the end of the track and so to the next...
This means that i will have to have the 'Jump to PGC start' at the end of each PGC while maintaing the next/back links from the original authoring on ReelDVD - is that possible?
cheers

Don't know for sure if that's possible.

Just try and find out. Save your ifo and then set a post command at each PGC to jump to the same PGC again.

The "next" button looks only for a chapter. If your PGC has one - say a second from the end then it would appear that by pressing the next button that you jump to the next PGC. However if each PGC is made of one chapter only - nothing will happen.

In any case, what you want will need some programming.
I think I'd do it with the Title button instead. (That calls VMG where you can add some IF commands)
1. Set a post command as Influenza suggested to repeat.
2. Give each PGC a GPreg number (how about 1,2,3 etc.)so that VMG knows which one is playing.
3. In VMG Title Menu ask if GPregX = 1(2)(3) goto Line 4(5)(6)
and lines 4,5,6 would be Jump to VTS_PGC_X / PGC_X

Thats the kind of logic you need there.

hi there again..
just tried Influenza's suggestion but the problem is that ifoedit(.95) only has the options of Jump to Title and Jump to Chapter (which also needs Title No) - not sure if Title means PGC but tried it and it did not work just continued straight to next PGC...
Maa - your suggestion seems more comprehensive but to be honest I dont know much about ifoedit - how to assign GPregs and where, what is VMG Title Menu and howdo i put conditions into it as you suggested (found very little tutorials for ifoedit...)
so, unless you feel like writing it down in a tutorial sort of way...
in any case thanks for al the sugestions and i will keep on looking...
- By the way Maa, it does recognise the PGCs as chapters (at least according to my PowerDVD software), each one as a chapter...
cheers
