When you drag the purple pinhead slider thing on the VOD timeline, especially to the end of the timeline, and press 'End segment at the playhead' it does not fill the end time correctly. It often is ahead by 30 or so seconds, but sometimes it really glitches and inserts a time from the first couple seconds of the VOD.

Sometimes it works by seeking directly on the video player; but a lot of times that has the same issue.
