can i reauthor a dvd so i can still get the menu functions but take out some bonus material so i can get a better quality burn. is there a way that the menu will functionally still work other than just playing through?
I assume you are talking about DVD Shrink? If that is the case, then no it is not possible.
In DVD Shrink you can replace items with a still image and conserve the rest of the DVD. I remove things like previews and unneeded documentaries and replace them with a jpg stating they were removed to save space. All the menu’s are still intact and I don’t have to compress the feature as much. You can also remove multiple comment voice overs.
