This also heavily QuickTime based and if you remove it there are less options for import and export. The rest of the program will work, however. Blackmagic have said they are working on changing this but we have no idea when. Blackmagic also have a free composition program, Fusion. This was a PC ONLY program which they have recently made cross platform so it works on a MAC as well. Ironically in the process the removed the ability to export AVI files from the program and replaced it with the ability to make QuickTime files, which, of course, actually creates a problem for Windows users that did not exist before.
