help shrink an anime DVD9 disc

[jarthel]

I have a anime DVD9 disc I want to backup into a dvd5 blank.

in the disc, there are 4 anime TV episodes with each episode having its own VTS (for example VTS1 to 4)

In the anime DVD, there is also a VTS for the opening sequence (sort of like an MTV) and the ending sequence (for example VTS5 to 6). These 2 sequences are the 1st and last chapter of each episode.

Is it possible to somehow delete the 1st and last chapter of the episode BUT when playing the episode, the deleted chapters will be substituted with VTS5 and 6?

thank you very much

Yes, it's possible, but not automatically. You will have to modify the navigation yourself, and that's not easy if you don't know how a DVD works. And it is not easy for us to help you if we don't know exactly how the DVD is structured and if we don't have the VM commands.

It is much more easy to leave the intro sequence of the first episode, and the final sequence of the last episode, and blank all other sequences, with VobBlanker.

I know a bit with editing commands using pgcedit and using the trace function to test it.

as for leaving the 1st intro and last sequence of the last episode, that is what I've been doing before using vobblanker. I was just wondering if what I asked is possible.

maybe you help point me to the right direction?

The idea is simple, but might be difficult to implement, if the DVD is complex or if you don't have a free GPRM.

You have to redirect the jumps to the episodes to several new PGCs in the VMGM, where you initialize a GPRM with a different value for each episode, and from where you jump to the intro sequence. At the end of the intro, you have to jump to another new PGC in the VMGM, where you test the GPRM to know which episode must be played, and you jump to that episode.

Use a similar method at the end of the playback of each episode to play the closing sequence. But in this case, if you don't need to remember which episode was played (for example to select the right menu button automatically), then you don't need to initialize a GPRM. Just go back to the menu.

I get what you mean. I'll try it.

thanks for the tip :)

I think I got it working. seems to be working fine when played using mpc.

thank you very much :)

ps. dvd command editing is almost akin to programming!

ps. dvd command editing is almost akin to programming!That's because that is exactly what it is.
