Have you read the docs on ffmpeg.org on how to use the libraries from MSVC? If your code builds in Debug mode but not in Release mode, you most likely have the use of linker references activated. Go over the linker settings for your Release configuration, you'll find it as the 1st option, I think on the Advanced page (well, it's the 1st line in MSVC 2010). Deactivate it, and you'll probably be fine.
(I'm a bit surprised though, I simply had inexplicable crashes...)
