Ok here's the problem. i burned a movie successfully with dvd shrink and then i went to re-author option to remove the things i didnt want. You do the re-author after the movie backed up right? well i went there afterwards, and chose only the movie to be recorded, no extras and stuff. It starts the encoding and when its time to insert the dvd, i insert the one i just recorded but it says wrong media or something like that, check your compilation settings. i mean what, i didnt do anything wrong, i followed the guide. i thought that the re-author happens before u begin burning, but frmo what it says, u first burn and then u re-author and make changes.
