it is working :D first I took clonedvd and made an dvd-RW. Enabled only the movie and leaving menu's........and dont delet tempfiles. clone dvd made for all ID nrs (1 til 12) an 0.ifo 0.bup 0.vob 1.vob most files are aqual in size exept VTS_01_0.ifo(bup vob) VTS_04_0.ifo(bub vob) VTS 4 plays the fbi warning 2 but not with all languages witch you can choose at the start of the dvd. okay i've loaded the striped movie into dvdshrink 2.3 and lookt in the menus to vind witch menu controles the first buttons. This is number 8. so in VTSM_PGCI_UT LU_1 (english) PGC-MENU_8 I changed postcommand 4 form If GPreg<0> != (cmp-val)<1><'then goto line# 8 [00 b1 00 00 00 01 00 08] to If GPreg<0> < (cmp-val)<0><'then goto line# 8 [00 f1 00 00 00 00 00 08] GPreg is never smaler then 0 so I could have deletet this line. post command 5 is (LinkPGCN) Link PGC 60 so with optie in the movie you choose anything, you will always go to PGC 60. ( saved ifo and get VTS en tested ==> step 1 finished) in LU_1 (english) PGC-MENU_60 i've changed pre command 1 to goto line 16 [00 01 00 00 00 00 00 10] pre command 16 (LinkPGCN) Link PGC 9 (there happends the actual playing) in LU_1 (english) PGC-MENU_9 ive changed cell playback: time still to ==> 0 playback time (BCD) to ==> 64 entry point sector to 204 ( the last sector of this cell is 205) If I take the same number, the movie keeps waiting for something) safe ifo and get VTS sectors Robin
