I have iMovie '09 and some .mpg files that can't be opened by it that i want to edit. I have been looking for some converters to DV or .Mov so i can use it with iMovie but all of them i need to pay. I'd much rather pay for QT Pro if that works instead of a 3rd party converter, so my question, can QT Pro convert a .mpg file? does it lose any quality?
