No picture or sound on downloaded video from iTunes

Question

I recently purchased a video from the iTunes store and I searched the forums for nearly an hour and couldn't find anything that helped. The file was rather large (2.18 GB). When it had "finished" it had an error mesage next to it "Network Connection Refused" or something along those lines. After that, it did not automatically load the videos into my "purchased" playlist. I had to manually track down the finished downloaded file on my hard drive. I added the file to my library in iTunes just fine, but if I try to play the video from iTunes (or after I loaded it onto my iPod for that matter)I just get a gray picture and no sound, yet the movie slider is showing the 3:07:55 and is moving as if a movie is playing. I haven't had any trouble with this in the past with music videos or podcasts or anything like that and I have sufficient space on my hard disk. Any suggestions would be greatly appreciated. Thank you for your time.

I have all the drivers updated for Vista Business (I have switched from XP Pro to Vista Business since I posted). When I had XP Pro all my drivers were up to date as well. I have had several videos work from before. What was interesting though was that because the file was so large (2.17 GB) I had to let the computer sit overnight. When it finished though, there was a network error of some sorts, though it showed that the download had completed. I said "OK" and thought that it would put it into my purchases playlist, but it did not. I had to track down the file manually and imported myself, but what I get is a gray screen when trying to play in iTunes 7 and a black screen when on the iPod. The interesting thing though is that the slidebar for the time is moving with no picture or sound. I think there may be something I need to do to the file, but not quite sure. Any ideas? Thanks!
