Greetings Meganxx,

Welcome to the Gnutella forums!

Your problem, most likely, is an issue with CODECs (coding/de-coding files necessary to play various videos) that are not included with WMP.

I recommend you download a better player, such as POT Player, that comes packed with virtually all current CODECs. The program is free and can be easily found on the Internet.

For more info on this and other tips for the best downloads (and which ones to avoid) see: http://www.gnutellaforums.com/downlo...ad-issues.html
Be sure to scroll down to the post from LOTR.
Enjoy!
