Also, there is a camera item that removes the GUI...
Requires client-sided script.
It's by Randy on the old RTB forums. (Which are getting nuked soon.)
It wasn't broken or messed up, it's just that playback was god awful and the .rec files were not used by standard video players.In short its pointless. You'd be better off making a stuffty movie with FRAPS, leaving the GUI up and all that jazz.
