Windows Media Player 9 Problem

I have a brand new Sony CyberShot 5.0 Megapixel Camera DSC P10 and I record mpg clips with it. Now, when I upload the files to my computer, the movie plays fine, but here's the explanation of my problem. Let's say I recorded a 20 Second Clip, when I go to play it back on my computer using either Winamp, or Windows Media Player, you know how there's a clock on the bottom right hand side of WMP, as well as a bar that moves along as the movie plays to let you know how much of the movie is remaining? Well as the movie is playing, the bar will already be at the end and the time will stop counting at about 5 seconds, (now its not 5 seconds everytime, I've had some times where it stopped at 10 seconds, my point is that it never reads the time accurately). Also, since the bar also is stuck at the end, I'm unable to search the clip properly, but the full clip does happen to play. Like the clip will continue to play through its entirety, but it does not read the clock accurately. Its so hard to describe, I hope I'm doing this ok. Anyways, normally I wouldn't mind this problem, but I want to edit this clip, to like make a nice little movie using Windows Movie Maker. Here's where the problem comes in, I'll import the clip into windows movie maker. When I view it in the storyboard, the clip stops where the clock does, so I don't have access to the rest of the clip since the clock stops early. The other 15 seconds of the clip don't play at all, it just ends after the 5 seconds that the clock does time.

I asked a friend to test the clip for me, and I sent him the clip. He's using xp as well and he was able to play the clip fine with the time clocking it accurately. It says 20 seconds. I want that to happen on my computer! Haha anyways I'd really like some help, because I really don't know what could possibly be wrong. Also I was able to fully play the clip without any problems in QuickTime. QuickTime accurately displayed the right amount of time and the bar moved in sync with the clip. If I find out anymore information I'll post it here.

 

It looked for all the world like a problem with the software creating the movies. Until your friend's computer entered the picture.

Try reinstalling all your codecs. Install all 3 packages from this page (Yes, even the ones for 6.4. There are overlaps and duplications, but they will not antagonize one another):

Then, this one with the VCM codecs that will support legacy encoders and apps, too:

Thanks Elvandil, but sadly after installing all 4 codecs, the problem still exists. There's got to be something wrong with my computer since my friend was able to play the files without seeing this problem. Anymore ideas?
