I see in the guide where it says to take 4500 - 200 - converted WAV size to find the correct number to input into mad dvd bitrate calc. to put into rempeg. My question is if my recording software handles burning ac3 and m2v then should I use the ac3 size to enter into mad bit rate? Also my dvd-r reads 4.38g in my drive so should I adjust the calculation to 4380 - 200 - converted WAV size.
