I have a 385 mb, 58 minute long AVI file that I downloaded a couple days ago and when I attempt to play it back it only plays about 30 seconds of it before restarting again . I have tried playing the file in both Windows Media and WinAmp and once the count timr goes down 30 seconds it stops and starts over again.

Does anyone have any clue as to what is going on and how it can possibly be fixed?

Thanks very much in advance to ANY opinions on this!
