I have a video that I just finished rendering in 3D Studio Max and whenever Explorer tries to render a thumbnail, Explorer crashes. The video has the AVI extension and if I rename it .TXT or something, Explorer doesn't crash. The video is encoded using the very standard Cinepak codec and plays fine in numerous players (even the seriously outdated WinAmp 1.1) without any errors. I've tried the file on 6 computers (all running XP Pro) and they all crash as soon as they try to render a thumbnail of the video. I've had at least 2 other videos in the past that had this issue too. I'm gonna re-encode the video using XviD which should fix the issue but just wondering what would cause this?
