You can also record a demo by:
First start a new game at the desired difficulty, any level. Then
> Options > End Game
> Options > Game Setup > Record Demo
Then open the console with ` and type "map dh03"
Demos will be saved as "edemo###.edm" inside the dukehard folder

To replay demos, rename them to edemo001
I find it easier to name the demos after the mod and map number, and if I want to watch it, I make a copy and rename that copy edemo001
