Problem Exporting .MOV with the Source Engine.

According to this: http://www.facepunch.com/threads/1125358, and this: http://developer.valvesoftware.com/wiki/Demo_Video_Creation(scroll to bottom to see), you can export .MOV’s from the Source Engine. I have no Idea if I’m doing it wrong. I do what I always do “record blah”(“blah”, as in my .DEM), “stop”(stop recording), “disconnect”(leave the server), “startmovie blah h264”(where “h264” is .MOV output), “host_framerate 60”(my desired framerate for recording), then “playdemo blah”(played the .DEM for recording).

Likely that this doesn’t apply for Gmod.
