corrupt mpgs?!?!?
 

I recently downloaded several movies in mpg format. When I went to play them in Media Player 7.1 it said the format was not supported. After some playing around I decided to open the file in Wordpad to maybe get a clue about what type of file it really is. I was totally confused when the first line contained "com.sun.java.util.collections.ArrayListM" among the code and continued with pathnames and references to limewire and other files I had downloaded!!

Has anyone else every come across this and/or have a clue what caused it and how to fix it?

thanx,
