I’ve had such a pain with my windows machine in trying to find codecs to play these files. “Mac Owners: Can you play MP4 files? Just wondering if you can play MP4 video files on OSX without having to install or buy anything. “I can’t Play MP4 video on quicktime, Please Help !!”
“mp4 files that won’t play on my mac but play on my PC? Is this a codec thing? Is there a program to convert these MP4 files for playing on mac os x?”
