a video clip that works fine in windows media player but not in Premiere

I have an AVI video clip file that I recorded from an old VHS tape many years back. The file plays just fine in Windows Media Player but when I import it into the latest version of Premiere Pro CS6 the video portion shows nothing but a green screen. The audio track plays fine. I've tried using Adobe Media Encoder to change it into a variety of different formats. Some don't even produce a file and some do but don't work any differently than the original within Premiere. Any suggestions?

thanx a bunch,

mike
