Sure youll probably get higher quality by increasing file size. Well, if youre like me you hate to change cds in the middle of a movie. Yeah you could scale it down but at a loss of quality...don't worry, the loss isnt bad actually its not bad at all! But the loss in quality depends on how long the movie is...ie if its 2 hours and 30 min, then fitting that into 1 cds would result in some noticeable quality degradation than say a 90 minute movie. You can do whatever you want but a nice rule to follow, is if the movie is going over 2 hours then its better to fit that into 2 cds, and movies that are in the 90 to 100 min range are great on 1 cd.
