mp4 files embed

I need a flash player or a solution to embed .mp4 video files downloaded from megavideo. I'm currently using JW flv Media Player for this, but it cannot play some files from megavideo correctly Update: You can find the current player and the file here: [login to view URL] The mp4 takes forever to load and when it finally loads, only the sound is working. The same file works fine in the megavideo player ([login to view URL]) Your job is to provide a solution (another flash player, a fix for jw media player etc) so the mp4 file on the server is streamed correctly, like it does in megavideo flash player
