DVD Shrink re-author question...

[low-fat-al]

I am re-authoring a DVD with DVD Shrink. I know this could be a silly question but how do you have it where after all what was selected to be re-authored repeat back to title one... In other words lets say you have 10 different clips you added to the DVD well after clip 10 is played the DVD stops ... how do you have it go back to the first title?

I don't think DVD shrink can do this but you can edit it easily with Ifoedit. Without knowing how the DVD is authored and what commands you have in the title PGCs, it's difficult to help you. Probably the easiest thing would be to remove any post commands in the title PGC of the last VTS and instead reset all GPRMs to 0 and call the first play PGC.
Do you know how to do this or you need more help?

could you explain in a little more detail... I have used IFOEDIT to try to figure out what you are talking about... I have 41 titles in my DVD...

[petar]

Open with ifoedit the last ifo file. If you have 41 VTSs then it would be VTS_41_0.IFO. Click on VTS_PGCITI and then on the plus. You should have only one PGC there. Click on it and scroll down until you see the PGC command table. You are going to put 17 post commands so if there are more, delete the rest (right click and delete). If there are less, add until you get to 17 (right click and add post command).

Then edit each one of them.
The first 16 post commands to 71 00 00 xx 00 00 00 00 where xx is from 00 to 0F (i.e. 00 to 09 then 0A, 0B, 0C, 0D, 0E and 0F).
The last one to 30 08 00 00 01 00 00 00

Save and that's it.

You have all the commands here for future reference

i have a question then...

the only post command there was a command for "exit"

I tried to just edit that command to redirect it to the "first play" and it just exits anyways...

I figured that would be the logical thing to do is just edit the only post command in there...

[low-fat-al]

I did it!!!!

there was a pre command that set values so I changed to a NOP and made a post command that called the first play...

the other method you told me about adding 17 posts and hex values stuff was a bit confusing so I experimented...

Thanks for responding and helping me through this issue...

[petar]

The last command of the 17 was the call-first-play-PGC command you used (I forgot ifoedit lets you select some commands so you don't need to type in the hex numbers). I suggested you reset the 16 registers to 0 "just in case" because I don't know how DVD shrink authored your DVD.

ok now,,,,


I tested my disc on a player and skipped to the end of the disc to see the behavior and after the last title it went to the first...

well i was watching tonight and it going from the second last title to the last and at the end of the last title it repeated the last title and kept repeating it...

I am lost.

There should be an easy fix to this...

I use Nero Recode or DVD Shrink to accomplish this simple chore.

anyone here who has any influence to the programmers should tell them to add a "repeat disc" feature on their RE-AUTHOR mode.

Does anyone here now a not so complicated way to do this...?

[petar]

I read again your previous post and you say that you've removed the pre commands in the PGC of the last VTS. Why did you do that? Also, just replacing the exit command with call first play PGC is not going to do the trick if there is some register value upon which the VMG jumps somewhere else rather than the first VTS.

The method I suggested of reseting all GPRMs to 0 and calling the first play PGC is a safe one to restart the play of the DVD. Just make sure these are the only commands in the post command section of the last VTS PGC. Why don't you do that? That's the only advice I can give you without knowing how DVD Shrink authored your DVD.

[low-fat-al]

I will try your method again...

one thing I noticed on the pre command of that ifo file.

it has "set gpreg<0> mov (set-val)<0>"

does that mean that the GPRMs are already being set to 0?
and if that is the case do i need to actually put all the 16 post commands setting those to 0?

[petar]

Means GPRM 0 is set to 0, not all GPRMs. If that command is in the pre command section of the last PGC and there are no more commands referencing the GPRM 0, you don't need to repeat it again in the post section.
You can browse through all PGCs in all the VTSs, note down which are being used and only reset those to 0 but I think you'll loose more time that way. Doesn't hurt to reset them all. That's what happens when you insert the disc anyway - reset all GPRMs to 0 and play the first-play PGC (actually all SPRMs also get reset to their default values but you don't need to bother with those).

great!! thanks for you help!!

well i tried it with resetting all and it worked while still on the hard drive, i am about to burn it to a DVD-RW for testing. I also just did it having only one post command to call first play... is it neccesary to have it resume cell 1 in that command?

I will let you know if it works...

[petar]

The call command stores a cell number for the resume function. If you issue a call command from the end of the video normally makes sense to resume it from the beginning (hence resume cell 1) but in your case it doesn't matter because you don't have any kind of menu anyway (i.e. nowhere to issue resume from). You can put whatever you want in there (or just leave it as 1 and don't complicate things).

thanks for the info...

well it worked and I can now finish my projects i have before me.

YAY!!!!
