Jackie Brown and VobBlanker+PowerDVD or how to resume...

[jsoto]

Hi all,

I was dealing with Jackie Brown, because a strange behavior when blanking, and I'd like to share the problem.

Well, this is the scenario:

Title 1 (main movie) and Title 2 (intro) are in the same VTS.

The DVD starts with the intro (Title 2) and goes to VTS01 root menu. Here you have a "play" button, which, after doing some checking about the current title (checks if sprm 4 == 1) does a resume (if sprm4==1) or a jump to title 1 (if not)

Title 2 has a postcommand to go to Root menu, which is converted into a precommand by VobBlanker.

Well, my conclusion after deep investigations, modifying the commands is: PowerDVD does not change sprm 4 to 2 because the title 2 does not really play,and keeps its initial value of 1. So when you press on "play" button, a resume is done, but no resume is possible!!. The effect I see is that : Title 2 (blanked) starts to play, ends and finally the DVD stops. In the original, because the title 2 plays at the beginning, this effect is not present, and PowerDVD plays fine.

PgcEdit in trace mode changes sprm 4 to 2 at the beginning of the precommands and the DVD plays fine

My two settops and WinDVD are also able to play well the dvd.

Conclusion: Is it a bug in powerDVD? (I'm using PowerDVD 5.0). This is the first time I know where a DVD is played in a settop and not in PowerDVD!

BTW, how the player knows the exact sector where go back in a resume? Title and chapter are in sprms but where is stored the current sector or time?

jsoto,
can you post IFO details (as obtained for example by PgcEdit)? That would be great...

jsoto,
have you also tried IFOEdit's playDVD? You can check the values of the gprms oops, I don't think you can check the sprms, darn!

BTW, I've used an unused gprm to add a condition to make the DVD work fine even in powerDVD, but this is not the matter

EDIT:
Play button is a "LinkTailPGC" command. There are other buttons which change gprm10 before doing the LinkTailPGC, checked in the first postcommand

IFOedit plays OK.

Only powerDVD don't.

The NTSC version looks nothing like that. backed it up using vobblanker 1.4.0.1 a while ago and works fine. but still weird

Three minutes late.:D
