PAL & NTSC on same DVD5 ??????

[srfscenar]

Well, the fact is that having a PAL and a NTSC video stream in the same layer in the same disc(!!!) is against the DVD Specs and that maybe some dvd players will crash when playing that disc.
BUT i have seen a DVD which had BOTH types made with Scenarist.

Does anyone have any clue on how the authoring was made???
I have tried many things but i still cant get it.

Thanx guys!

Scenarist is very strict with tv systems. It doesn't allow u to import a pal video in a ntsc project. Perhaps the title set it was tempered with ifoedit. if it was a dvd-r what u saw.

I apologize for my english response but its an english speaking board.

It wasn't authored with Scenarist. It wouldn't happen if it was. Perhaps some cheap home solution, we have plenty of them in Greece, could caused it. U know a project that starts as NTSC and switches to Pal.

first of all i wanna apologize for my GREEK on the 2nd post.I wasnt thinkink!!! Sorry all!

What i said before is that the DVD i saw wasnt a DVD-r but it was a dvd made from production. I have some very good sourses that told me that it CAN BE DONE with SCENARIST (and it was made with Scenarist) but there are some steps that must be done. Has anyone tried it?

This is possible with a little messing about.... I've posted this info b4.. and every time one of the long-time users usually jumps all over it stating that mixing video formats is illegal DVD format.

It might be illegall according to DVD standard but it is often done.. I've seen it many times commercially.. latest instance is "The Animatrix" PAL R2 rental version...

VTS 2.. the bonus material VOBSet has NTSC menu.. i'd post the IFO but anyone interested enough can check if from above info...

the easiest way to do it I've found is to do 2 re-authors... 1 for the PAL content... 1 for the ntsc.. using dummy source except 4 the content required. Combine the 2 lots of VOBs until you have layout matching original and the treat as normal....

well ak47, persuaded by your persistance I made such an image of mixed system sources and guess what. It loaded OK in my Philips, played the Pal section OK but it sucked upon NTSC one.

In a Affrey LD1020 it refused to play at all. This is odd however cause this standalone has pc ide cable and a Pioneer dvd-1017 in.

In my pc it played the PAL OK and managed to play the NTSC part with a ton of hickups.

So I guess that it isn't a viable solution. At least for me.
I would rather undergo the fuss of transcoding NTSC to Pal and be in the safe side than having a hybrid disc that would play according to its will.

odyseuss...

I agree.. this structure is some kind of hybrid and might well perform unpredictably.. depending on hardware...

but I would point out that I never suggested that it's ideal, or without problems.. just that it is possible.. and that I had seen it commercially on several occaisions...

to be honest I can't really grasp why they do it.. especially on the title mentioned..

[oddyseus]

I quite agree with u.

I ve been in the pc realm almost 25 years now and I come to believe that everything is possible and that always there is a trick to fool a computer to do what u want.

That said, the expression 'can't be done' actually means that
1. it wont be stable,
2. too difficult,
3. Not worth it
4. Result/time needed isn't worth it, etc.

In this case I think that 4 is applicable.
