Maybe I can help? Here's the software I used to make my videos:
-LoiLo game recorder -
http://loilo.tv/en/product/game_recorderThis is what I use to record the game. It's free because it comes bundled with a trial version of the company's video editing software, but I can confirm that it never bothered me about trying it or buying it, so it's not been intrusive. It's not too hard to use, you simply check that it's targetting the game and then press record.
-Freemake Video Converter -
http://www.freemake.com/free_video_converter/After a video is recorded it's usually a really big file, so I open it in this, select to convert it in MP4 format (for youtube) and adjust the size to be more reasonable (usually somewhere between 500mb-900mb depending on video length so the quality is still decent).
That's really all there is to it, you obviously need a microphone of some sort if you want to record your voice over the video (the game recorder should recognize the microphone). I'm sure it shouldn't be too hard to find more info on how to use these programs, either.
I've been both very busy and playing other games when I have free time so I haven't touched DD or my planned videos in a long time, but I'd love to see more people make videos of the game! I'm still thinking of getting back to the game and record more when the time is right
