Want to record your own demo? Yes you can easily record the demos of how you play; this can be much beneficial if you want to remove the problems and improve as a better player or just to show off your best shots after making a movie.

We can make the demo easily while playing and without using any software or application. The demos are recorded in .dem extensions and takes optimum space.
Steps:
• At the point you want to start recording your demo, bring up the console.
• Type “record XXX.dem” in the console, where XXX is the name of the dem file.
• The recording will start instantly and will not interfere while playing.
• When you are through with the recording, then just type “stop” in the console to stop recording.
• The recorded demos will appear by default in either the “cstrike” folder or the “czero” folder (depending upon which version you are playing) in the installed game’s directory.
• To view the recorded demos just type “viewdemo XXX.dem” or “playdemo XXX.dem”, among which the command viewdemo is better as it allows fast forwarding etc.
I may be providing this post bit late but better late than never. You can also convert your recorded demos to movies, refer this post.

I’ve recorded a demo once and when I tried to play it, it cuts off and says “You’ve been disconnected from the server Reason 8″.
SUP!?

Do one thing, first of all ensure that your extensions are ON (from Folder options) and then arrange them by type or search for .dem file
