I have a .avi file that I would like to burn to a DVD using iDVD. I tried importing the .avi through iDVD itself, which resulted in an error. I used ffmpegX to convert the .avi to what I thought was DVD standard, but it resulted in three files that iDVD does not recognize (.ac3, .m2v, .wav). The point of my question is, I realize that the .avi file is already compressed. I know I could convert it to a .mov or something and that iDVD would take it, and then compress it again. I am trying to avoid the extra compression step and convert it to an output that iDVD will accept and not recompress. What format should I output to? Thanks!
