PS3 for Front Projectors : Epson PowerLite 77c & Epson PowerLite S5 RCA input b – no HDMI input will ps3 work?

I’m reading articles online stating that the ps3 and Xbox 360 users are dissapointed that these projectors do not support HDMI Input, but can a PS3 still be connected to these projectors if they support the standered RCA components?

Or, inorder too connect any projector to a PS3 I would have to purchase one that supports HDMI? the projector also supports S-Video Input also if that makes a differents….

As you can see I’m pretty cluless to what projectors support the PS3 console. PLEASE HELP

thankyou for you time
