Hey Mac-forum,
I have a question regarding opening up some Mpeg-1 files. I get an error message saying "This is not a movie file" when I double click on it. The message has that Triangle with the exclamation point in it.

I've downloaded Perian for my quicktime and that helped with some of my Mpeg-1's. I don't understand why a file with the .mpg extension isnt recognizable as a movie file?

Any Help is appreciated! Thanks
