I downloaded part 1 and 2 of a movie and to start I thought it was odd that part one is an .avi file and part to is an mpg. But what I really can't figure out is how to play these - using windows media player i get an error that the player either doesn't support this file type or does not support the codec which was used to compress the file.

i confirmed that WMP is setup to autoupdate codec and i tried playing both of these files using different software out there...should I just assume that these 2 files are corrupt or am i doing something wrong?
