Hi rjzzz420,
Your probably missing the codecs needed to play the files. Try playing them in a different player.
VLC media player is a good one with the codecs built in and will play most any file.
XP Codec Pack 1.3.0 is a good codec pack for windows media player. Be sure to install it after you d/l it.
More info on codecs and media players here:
CODECs list and alternate players for Movies
A lot of movie files are either fake or corrupt. Learn to use "Bitzi" it will help tell you which movie files are good or not:
