I searched the forums and didnt get a direct answer so heres my question: Blank dvds hold 4.7GB...I have a .DV file about 7GB. Toast lets me burn it...but I was wondering if there was some kind of compression used, and maybe i couldnt really notice the difference when I watched it? It looked normal. I was thinking it could either be compression, or that it doesnt burn under the size of the file, but maybe the length (2hrs.) Could some one let me know what goes on here?
