Re: PC + PS3 + HDMI Switcher = WTF? (ie Help me)
Sounds like an issue with the switcher. I have one myself (though not by Belkin, just some no-name brand switcher from partsexpress.com), and I have my 360, PS3 and HD DVD player connected to it (3 to 1 automatic switch). Haven't tried 1080p signals on it yet though , but it claims to take 1080p 60hz and other stuff.
