I prefer seamless branching so I can choose on the same disc (like The Abyss), but sometime I wish I could choose which scenes were re-insterted. Like leaving out the scenes from Aliens showing the settlers at the begining, but re-inserting the automatic sentry cannon scenes.

Yea I know I'm asking a lot. but then I'm sure one day this will be possible.

Maybe there are some DVD players out there which will allow you to program each scene you watch, but not mine... Yet!
