Is there a guide to using a DVD instead of a CD or 2? I would really rather have an unattended install on DVD which install MOST of my apps that I use everyday.

Its the same process, you just have one DVD instead of two CDs... Just follow the tutorial for one CD, but put it all on one DVD and you should be fine!

Also, for Multi-Boot DVDs: http://flyakite.msfnhosting.com/

Excellent, I am mostly interested in using a DVD because the size of the applications I wish to install. I suppose I can just use the unattended walkthrough and burn the files to a DVD? Is there a specific program I should use to create the ISO for DVD? Is the procedure exactly the same for creating a DVD?

Exactly.

I followed the MSFN guide, result with adding drivers for all my devices, patches, updates, etc. With no extra apps, it was over 800 meg so when burning, so I just used a DVD instead of CD. Works great!

no special program required to burn the iso to dvd, as long as your burning app supports burning to dvd media and you have a dvd burner of course.
