I am assuming this is still impossible, but I thought I'd ask. I have an early 2010 MBP (no Thunderbolt) with Firewire 800 / USB 2.0 Is there any way to get HD video input to show up on my screen? I understand it would take some kind of adapter. I ask, because I'd like to use my macbook as a monitor at a gaming LAN this summer instead of buying a monitor. Thanks!
