For video recording I use Fraps. The free version gives you 30 seconds of footage. I then use VLC player to compress it to an AVI and then I chuck it on YouTube. It's not great quality but it works for me! If you want to record a video longer than 30 seconds, you can record multiple 30-second clips and then stitch them together using VLC.
I look forward to seeing more of your system in action, it sounds really unique!
