Installing Ubuntu 12.10 from Live DVD - won't load, screen goes blank

http://askubuntu.com – I'm trying to install 12.10 from a burned DVD. When I try to boot from the disc, I'm met with a Grub screen that shows four options (the standard "Try Ubuntu without installing" / "Install Ubuntu" list). No matter which option I select, the DVD spins for a bit and the screen goes black. I've tried multiple verified Live DVDs. I also tried using the wubi installer; upon completion, my Windows Boot Manager does show the option to select Ubuntu, but when I click it brings me straight to a black screen with white text that says "Windows failed to load" and either takes me back to the Windows Boot (HowTos)
