Yeah, if you've got a digital camcorder that takes video input through the ports (mine takes either svideo through the svid port, or composite through the '3 in 1' port minijack) then all you have to do is run the cable from your xbox video out (the video cables coming out of the back of that proprietary plug on the back) and plug them into your digital camcorder. Record the video you need (this should be self explanatory once it's hooked up) and then feed it into your computer via a firewire cable and the application 'dvgrab'.
Edit with Kino or whatever you'd like (If you are a power video editor, I'm sure you know what you want, if not, there are quite a few of choices for you to pick from), and Output to a DVD with growisofs and a DVD Burner. Or, if you are just planning on keeping the avi's, be sure they are playable with other OS's and other media players by compressing them with codecs (using mplayer/mencoder) that are on everyone's machines.
