seems the problem is as follows This is a matter of great sorrow that there is no converter software for converting .dm_1 file to .avi.
however
Option 1 Using fraps (recommended): When running a cod4demo of your own through console command,use fraps to capture that demo in avi format.Later you can upload it to youtube. However the advantage of doing this in COD is that the low fps you get from recording wont effect your gameplay as your watching a video of yourself. This option takes a lot of HDD space and gives nice quality.Its high quality and easy and takes a lot of space but it will not provide a smooth demo because you playing back the demo and capturing to fraps. Option 2 Ingame command: This option will give you the best quality and smoothness,but it does also require a hell lot of work.And also you will not get sound in that demo.Playback your demo, and type /cl_avidemo 30 in the console, your screen will go fairly jerky and your FPS will hit the floor. What it is doing is taking a screenshot 30 times a second. Once you have your desired footage, you will have a LOT of screenshots in your screenshots folder. What you need to do is convert these from TGA to Jpeg.Use Reaconverter to convert those TGA files to jpeg.Reaconverter is available fromhttp://www.reasoft.com/products/reaconverter/
And yes all this will not correct what Dean is having a problem with which if anyone has had this problem or know of someone that may have ...He can play back via COD4 video player but all mods do not work.....ace/ftg1/ftg2/mwf etc
SO ? IS WHY IT WILL WORK ON SOME BUT NOT OTHERS AND REPORTS A WEAPONS MISMATCH ERROR WHEN ATTEMPTING PLAYBACK
