Why should I need both QuickTime X and QuickTime 7 on a Mac Mini 10.8.2 to play video files I created on a Mac. Was QuickTime X designed to a lower standard ? If the answert is to get VLC playe,r why not just delete Qicktime all together and be done with it.
Answer depends on your viewing requirements. No media player plays everything. If one particular player handles your particular mix of file types and compression formats, then you don't "need" the others. If not, then you may need more than one player.iMac, OS X Mountain Lion, 3.4 GHz Quad Core i7, 12GB 1333 MHz
