ok cool. so i've used a bitrate calculator and determined that i would need a bit rate of 1007kb/s, however, i am still having difficulty with the numbers. are you telling me that even tho when i choose the file and it takes up 750 mb of space on the dvd, that is irrevelant? also, do you recommend any specific programs for changing bitrate? i came across river past video cleaner pro, and upon running the program on 1 file, it whittled it down from 300 mb to 121 mb and has a new bitrate that apparently fit to my needs, but when i used the dvd editor in nero, its still coming up at using 700 mb's of space. am i missing something obvious? thanks
also, you say that this scenario is all about the length of the movie. is there a standard length that 4.3 gig dvd will hold?
