Thumbnail breaks upon thumbnail regeneration

Hello,

I just recently upgraded from 5 to 6. I have my Flashvideo set to regenerate thumbnails, but they don't appear in the player when I regenerate them. Here is what's happening:

-Upon first uploading the video, the thumbnail is generated and displays fine

-If I regenerate the thumbnail, it is visible as an image in the teaser (due to content template), however it doesn't show in the player

-Looking at the file, upon regeneration, it adds a duplicate fid at the end of the file name. For example, if the file is initially "video_4321.jpg", then it becomes "video_4321_4321.jpg"

-When looking at the code of the video page of the broken player, I see it is calling for "video_4321.jpg", and so it doesn't show up in the player

So how do I make it not add that additional fid to the thumbnail? Or how can I make Flashvideo not call for the old thumbnail file name?

Any help is greatly appreciated, thanks!
