I know it's old but it has OS X Version 10.4.11 & my quicktime player is 7.6.4 (PRO) & my Flip4Mac WMV is 220.127.116.11 along with downloading Perian 1.2.1. So why is it that when I trashed my 10 year old PC and transfered all of my videos (mpeg,mpg, etc.) it won't play on my computer still?? I figured I have done everything correctly from reading these types of similar problems but when I click on the file and quicktime pops up it says " the file is not a movie file". This would be alot easier if I was not deployed at the moment in Afghanistan I understand that but this is my only source of watching movies from home. Any help would be much appreciated. Thanks for your time.
