Ok, I've got a bit of a problem here. I'm going to be having AT LEAST 3 480p sources in my HT being fed to a Sanyo Z1 projector. 1. DVD, 2. HDTV cable box, 3. Gamecube. I'm not sure if my PS2 supports it, but if so, I'd like to use that as well. Problem is, my B&K Reference 20 has NO component inputs at all. What would be my least expensive solution to this problem while maintaining the qualities of the source?
