I've just tried using InstantCopy with a DVD-9... I have downsampled alot of the video through this program until it told me that I've reached the "4.31 gb" limit. One hour and 40 minutes later, *.pdi - *.pdi03, states that the entire movie is now _3.90 gb_... What happened to the 400 mb? Is this size representable of what I will actually be burning?
