first make sure you have added the NTSC fix files from the DVD-ROM folder into your VIDEO_TS folder then download this file:
EXTRA PAR2 FILE
once downloaded unpack the rar file and put the file it contains into the VIDEO_TS folder .
now right click on the par2 file in the VIDEO_TS folder and select "open with.." and select "quickpar" (you may have to browse if it isn't in the list". let it scan all the files and say "ready to repair using...." . Click on "Repair" and sit back. the repair will take a while depending on your setup. Once its has finished repairing then close the program and make sure you take any par2 files out of the VIDEO_TS folder but DON'T put them in your DVD folder. place them elsewhere on your PC. Also make sure you delete any files that have a .1 extension in the VIDEO_TS folder too.
Now you need Pcgedit. install pcgedit if you haven't already got it. open it and select "file> open DVD" and select the VIDEO_TS folder that you have added the fix to. now pgcedit will start scanning the disc and a new box pops up. don't do anything until you see the "close" button that will appear when the scan is done.
Once this is done goto "file>BURN DVD/ CREATE ISO" and select that. A new box will pop up saying "DVD saved ok". Click ok.
Now in the next box that appears make sure DL media type is selected as "Double layer DVD+R". Goto "output ISO" and select where you want the ISO file to be stored ready for burning later. Just name the "volume label" star wars 4" or anything you want.
once you have done this click "ok"
Another small box will pop up telling you there are other folder and if you want to burn them. Just click "yes"
Next another box will appear. This is the layer break box. In the top section of the box "cell 28" should be highlighted blue. If one of the others is highlighted just click on the line containing "cell 28" then click "OK"
Your new ISO will be created
You can then burn the ISO image file with Imgburn (best one to use for windows users and it is included in the DVD-ROM folder. Not sure if there is a mac version or the version in the folder works an MAC) or nero or similar
if you use imgburn make sure that when the layer break box pops up when you go to burn the disc you highlight the layer break and make sure that "don't update IFO's" (it says something like that but can't remember) box is ticked and burn
ALL should be fine now and i updated the last fix post in case it caused any confusion. If you get any errors while creating the ISO with pgcedit then you ahve done something wrong in the first steps.
