When converting avi to dvd,i always write to a hard drive folder first, then use nero burning rom to finish project. My question is when i'm setting up nero vision to transcode to dvd, it tells me the project is going to be to big to fit on the dvd. I then write it to a hard drive file instead, with all settings in high quality. After the transcoding is done i go to the burning rom [but what i notice is that the size of the avi that nero warned me about has reduced to something less than my dvd+r9 can hold.] My question is is nero automatically dropping the quality of my avi or i this a normal drop in file size during the transcodeing process. I'm worried i getting an invointary loss in quality and i would like to maximize my dvd space.
