I really hope someone can navigate me to dissect this issue because I have never had this happen or even heard of it happening before, but if anyone can help solve it that would be greatly appreciated K.. Here goes.. I have movies on my computer Mp4, avi, etc I have watched these movies before, many times in the past . Just recently I have tried watching and opening several of my movies in EVERY player imaginable (VLC, MPlayerOSX, Quicktime, Quicktime pro 7, iTunes), and nothing will play them all of a sudden APPARENTLY my movies are not recognizable files, this is the message I get every time I try. . Even though I have watched them many times before a few months back. .. Anyone care to dissect this stupid issue?? Do I simply need to update something for ALL of my movies to be recognized? I find this absolutely unreal. Thanks all.
