Need help switching video sources

[Cidien]

Don't know where else to post this, but I need help with my ps3. I'm currently using HDMI and want to switch to component on another tv. I don't know how. Switching in the settings doesn't really do anything as switching to component while hdmi is hooked up (so I can see what i'm doing...) just goes to a black screen which will reset eventually. How am I supposed to do this? Am I missing something obvious?

Why can't it just be like the 360 and automatically detect what's plugged into the Fn thing? I can't imagine that would take a huge chunk of time and money out of their pocket... at first I thought it was just a defective ps3 until my friend tested his and the same thing happened.

Anyways, now i'm just ranting. Any help would be much appreciated.
