I want to find a particular one which should provide some lols, which program should i use?

download the source tv file,

my computer, program files, steam, steamapps, yourusername, css, cstrike and copy the file in there.

launch css, type in console play demoname

ahh danke sir.
quick time player just, didnt work

id have been surprised if it did work :O

so your saying...it wont work!? jesus wynney make your mind up!
ok im still looking for an answer
ill try it later

What Wynney said was right. The demos store game state data, they're not movie files. You need to play them in the game.

Quick Time won't work becuase it's not a movie file.

i said id be surprised if quicktime works, the way i told you to do it definitely works

OHHHHHHHHHHHH GOT YA!
