I have a 2 year old MacBook and want to burn a DVD that is 8000 Mb in size. I extracted the files from the DVD and compressed them down to 4400 Mb but the quality is no that good and the picture is squeezed and elongated. Can my 2 year old MacBook burn a DVD 9? If yes, how. Secondly, can I get better quality by using a different video conpression to get the file sizes down to 4400 Mb? I used RipIt and DVDMaster. TIA
