Gmod doesn't ask for codec when i do startmovie!

Im trying to use source recorder to record an engine i made, i already recorded the demo file successfully, but now when i do the rest of the steps, no movie file is created, also, gmod never asks me for what codec it will use when i type startmovie engine avi

Any suggestions?

Try reinstalling Gmod, or just deleteing your garrysmod folder.

No do both.

I get this too.

I will probably just put the dem file on my flash drive and use another computer to render it.

I found that if I press Ctrl Alt Delete, click cancel and return to desktop the codec selection is there
