Movie downloads but only audio plays?

[Steelkiller]

Ok, so I'm new to movie downloads on LW so maybe this is an obvious answer. I have downloaded 2 different movies and the same things happens when I try to play them on Windows Media Player. Only the sound is played? It's the correct sound, but no picture, just the little light show that WMP does when your listening to something. I am sure that I downloaded a video, not just audio, just can't figure out what I'm doing wrong. Any help would be much appreciated.

You might need codecs for your WMP. Check out the link below. I've used the XP Codec Pack.

Or, you could try VLC player. It's free & has codecs installed. It's very reliable. There's a link for download, plus more info above.
