From the first post of the thread:
How to watch recordings:
1. Go to
http://dedcon.net/ and download the latest version of the program.
2. Install Dedcon.
3. Download the recording(s).
4. Open(Double-Click) the recording file(*.drec), which should now have a file association with dedcon. A black text box will pop up with the names of the players, and the pre-game chat log.
5. Leave Dedcon running, and open Defcon. In the server list, you will find a green server called 'playback'. Enter it to watch the recording! Sometimes it doesn't open right away, so just hit refresh until it shows up.
