Minority Report R4 - ifoedit problems so also used dvdfab
Tried to split the above DVD using ifoedit. After all the processing ended up with two disk images that produced navigation errors when played in ifoedit. Tried the usual tricks of altering First Play PGC Pre command to go to Title 1 but the error remained. Also had no joy in removing the copyright warnings or the 20th Century Fox Logos at the beginning. Finally prevailed with a bit of hack resulting in not total solution but workable
Resplit the disc with dvdfab. With dvdfab the first disc is playable (albeit with copyright warnings and studio logos) fine in ifoedit as well as a burnt disk. However the second disk gets illegal navigation errors. Accordingly went to the second disk image created by ifoedit and edited the video_ts.ifo file as follows: 1. Altered the First Place PGC Pre command to go to the First Title. If I only do that the illegal navigation remains 2. Then went to VMGM_PGCI_UT to each LU_1 entry looking for a Pre command in the PGC Command table. In my example for the first menu entry it looked like this PGC Command Table: [000000ec] Number of Pre Commands 1 [0001] [000000ee] Number of Post Commands 0 [0000] [000000f0] Number of Cell Commands 0 [0000] [000000f2] Size of Command table in bytes 15 [000f] [000000f4] 1.Pre Command (JumpTT) Jump to Title: 1 [30 02 00 00 00 01 00 00 ] Note that I have changed the Pre Command to Jump to Title: 1 Did this for all the menu entries and voila, when the second disk is inserted it starts playing the movie as I want. The only strange behaviour is, it starts playing the movie from 60 seconds from the end of the first disk :-) In fact that 60 seconds is a separate chapter and if I press chapter forward on my remote it starts the movie at the right place, presumably at the layer break. I can only surmise that the problem is due to splitting the DVD using two different software packages and using one split from each but I can live with that I can't bring up menus playing disk 2 but the menus are not important and most of the options can be selected on the fly with the remote control (language, titles etc.) This is certainly the hardest disk I have had to work on so far Larry Just to provide more information. One one attempt I took the disc image created by DVDFab and did the above PGC editing. That also worked but created a really strange result. Upon insertion of the second disk the DVDFab menu came up saying Please Insert Disk 1. In fact this menu occurs as 11 chapters! So on pressing the skip chapter button on my DVD player 11 times and still seeing this screen, on chapter 12 the movie started at the right place! This is pretty strange and I don't pretend to understand this at all Last edited by lchiu7; 25th August 2003 at 01:39. |
