One DVD -/+ RW
First off, you need to rip the dvd using the file mode option in DvD Decrypter. Make sure you select EVERY file. Once this is done, its time to figure out which of the VOB's are the Movie files. This is generally a very simple thing to do, but just incase, they usually end with a file size of "0.99 gigs" and are numbered sequentially, i.e "VTS_01_1 , VTS_01_2 etc". Keep in mind however, that there will be to sets of VOB that are numbered sequentially. One containing the 4X3 version, and the Other the 16X9.
Once the files have been located, and you've decided which of the two you want to keep (I usually choose 16X9 for personal reasons), its time to get rid of the files.
I'll use the movie "National Security" as an example. The widescreen version comes on the "Vts_01_.vob" title set (with vts_01_0.vob being the main menu). While the Fullscreen Version comes on the "vts_05_.vob" title set (with vts_05_0.vob being a filler vob).
I'm assuming that you'll want to keep the widescreen version and get rid of the fullscreen version. So, all you have to do is delete the VOB'S containing the fullscreen version of the movie, in this case being vts_05_1.vob and all the rest in its title set. Make sure you leave the vts_05_0.vob file as it serves as a place holder.
Ok, now that you've deleted those, fire up IFO edit and open up the Video_TS.ifo file. Once its open click on the "Get VTS sectors" button. It'll ask you if you want to process all the IFO files, click on yes. For some reason IFO edit never process ALL the .ifo files for me, so i'd suggest that you open all the other .ifo files manually and click on "Get VTS sectors" for each of the .ifo files.
Ok, now that the dvd is structured correctly it should play fine in most DVD players, however, if someone were to click on the fullscreen version button while playing the dvd, the DVD player would lock up. We can remedy this by using MenuEdit. Fire up MenuEdit and open up the VOB file that contains the widescreen/fullscreen selection menu. In the case of National Security, that file would be vts_01_0.vob.
You should now be presented with a collapsable menu that lists the VobID's in that particular file. This is where it can get a bit tricky, you need to find the particular Cell ID that contains the widescreen/fullscreen selection menu. MenuEdit helps you out with this by listing how many buttons are in that particular Cell ID.
BTW you can check exactly what a particular Cell ID is by double clicking it, it'll give you a basic view of how the buttons are laid out, which should help you in discerning which CellID is which. For National Security, we know it has 2 buttons, so we look for the Cell ID that lists 2 buttons. Again for National Security, this particular Cell ID is under VobID 1 > CellID 4. Once you've found the CellID, delete the button that links to the fullscreen version, you'll be asked to save, do so.
****NOTE the rest of the guide is written for the Latest Version of NERO Burning Rom
After thats done, you're all set to burn the compilation. You might encounter a "DVD file reallocation" error when using the "DVD-Video" setting in NERO.
If this is the case you will need to burn the compilation using the "DVD-ROM (UDF/ISO)" setting in NERO. All of the settings should be similar to what you see when you burn a DVD using the "DVD-Video" settings except for the UDF tab. All that needs to be done on this tab is to check the "force DVD-Video compatibility mode" box.
Adjust everything else as you would normally. Once thats done, click on the new button. Everything should be similar as to what you see normally when you choose the "DVD-Video" option, with exception that the compilation doesn't have the standard "VIDEO_TS" and "AUDIO_TS" folders.
Just right click the compilation and choose add folder, make sure to create two folders, one labeled "VIDEO_TS" and the other "AUDIO_TS", without the quotation marks. Once that's done, just move you're DVD files into the VIDEO_TS folder and burn away. You'll notice that the error message is gone, let NERO do its thing, and hopefully if you followed the directions as listed, you should have a working copy of your movie =D.
AS WITH ALL NEW THINGS, PLEASE PLEASE PLEASE USE A DVD-/+RW, you'll save yourself a great deal of money and frustration with these.
