Hey guys!

I'm recently in a project for making a CS:S movie. I'm recording the footage with the built-in source recorder. Here's what I plan to do and what most people suggested:-

Read for with source recorder
Watch and have fraps running and recording.
Edit movie.

They suggested this because fraps requires a very good PC to record with fps lag. Source Recorder causes no FPS lag at all.

After I have recorded all my footage, I try to open them and nothing happens! When I open CS:S and try to open the demos it says "Only one instace of the game can be opened!"

Ideas?
