How many video parts can you Unselect?

If I just want to have the main movie on the DVD and don’t care about any of the extra things tha tmight be there, can I just unselect everything except the first line in the video files that is the actual movie itself?

Is there any danger in unselecting too many things tha tmight make it not play? I havent’ had any problems so far unselecting just about everything (which gets the percentage up to almost 100% most of the time) but just thought I’d check on how others do it.

If selecting everything goes under 65%, then i select the main movie only, else i select everything.

No, there’s no problem in selecting only the main movie, it will play just fine.
