Adobe Mpeg Encoder Activation How Do I Get MPEG-2 Files To Import Into Adobe Premiere 6.0?

How do I get MPEG-2 files to import into Adobe Premiere 6.0? - adobe mpeg encoder activation

I have a computer with Windows (Vista). If you do not import a preview image will not play, and usually freeze the program when I try to play. I read something about buying a TV card, but I'm not very smart when it comes to that. Is that what you need?
