Streaming a .avi video on xbox, closes after two minutes. Help?

I'm watching a TV show thats in .avi format that i've downloaded on the 360, through 'Vuze's' Xbox 360 Devices. All of the episodes have been fine so far, but one stops after 2 minutes 13 seconds. It works fine on the computer, and when selecting it on the xbox it says runtime 46 minutes, but when I start the video and bring up the info bar, it shows the 2:13 time remaining. I've also downloaded the episode from two different sources now and the same thing happened, although theres a chance they could have both been the same file. Any suggestions? Thanks.
