Watched Length Bar overextended

I really watched the hell out of the mailbag ;3

I have the same problem with the same video (KANE Cups). The site thinks I've watched 842% of the video. It is probably because the video is reportedly 1 minute 20 seconds long, but it's actually 20+ minutes.

There were some shenanigans between this video & some random Need for speed video that gamespot did apparently. If you hover over the timebar while watching the vid, you even see the NFS footage pop up.

Yeah, I'm not entirely sure what happened with that particular video, but let me know if you see this occurring on any other video so we can get some more data points. Sorry for the trouble!
