Video problems since IT'S Gingerbread update

[IronBeagle]

Since the Gingerbread update sometimes videos will not play on my Thunderbolt....if I go back to my videos that I took with my phone, they just have a still picture but you can hear the sound of the video playing. When I reboot it will work fine for a while and then do it all over again. Anyone else had this problem? Any one know what fixes this? I am not replacing with a refurbished phone! Thanks
