Weird WinMediaPlayer10 issue

[Niccohel]

Hi all,

I'm not sure whats going on, but some of the videos I have on my computer play funny. For instance, I have a vid (its an mpeg) thats about 78k. That should be around 6-8 minutes, maybe longer, but Windows Media Player 10 says its only 1 minute long. While playing the video it only plays the first minute, but if I click on the cursor bar thing at the bottom somewhere near the middle, it will... jump... to about 4 minutes into the video, and continue to play for the remainder of the half minute worth of displayed time.

It does this on various home videos, downloaded videos, and even on some vids I downloaded from a friends camera.

Any ideas?

Thanks.
