IFOEdit allows you to strip audio and subtitle streams you don't need, to get rid of certain menus and extras but still preserve the general DVD structure.
IfoEdit also allows advanced changes to the .ifo files (which contain the "logic" behind DVD playback) to edit out region codes, RCE protection, change menu links, etc.
Changes in IfoEdit 0.971
- fixed: NTSC authoring problems (2).
- added: Programs in PGCs can be added now even if there's no program present already.
- added: empty PGCs can be added now to VTS_PGCITI
- fixed: In VOB Extras, the 'Remove Angle' option was always greyed out under XP.
So for instance you could get rid of the annoying FBI warning, delete audio streams you will never use, and bring the size of the movie down to a point where you can burn it onto a recordable DVD media. And if all the stripping doesn't help you can always re-encode the video and simply replace the video stream the DVD has with a lower bitrate one.
