mpeg video help

I have several simpsons episodes on my computer that are in mpeg format. They are normal sized, but when I try to watch them, it shows that they are only about a minute long. If I scroll through the episode, it shows me different parts of the whole episode, but only goes for a minute. Any help on how to watch the whole episode would be helpful.

 

See if updating codecs will solve the prob.

Download and install K-lite codecs:

Thanks for the help, but I figured it out. I just downloaded a converter and converted it to avi.
