This is a fix for CoD4 so that the connection interrupted error when your using a 
higher avidemo or a slower timescale like 0.001 the messege and the icon will never show again
1.First make a new cod4 folder just for movie making
2.Copy al the files from the original cod4 folder into the new folder that you have just created
3.Copy the fixed iw3mp.exe in that folder and you good to go
But if you just copy the fixed im3mp.exe witout making a new folder just for movie making maybe you will be banned by punkbaster
IMPORTENT:then you run the fixed im3mp.exe go to multiplayer options and set punkbaster to NO
