My amp is Marantz. I use a splitter from an RCA Monitor out, one to the tv and the other to the projector. Switching is no problem, but extreme loss of signal! Not only that, but my projector doesn't decode the Macrovision signal so I also have a video stabilizer inline of the RCA. Just a real crappy signal. I was hoping that somehow, there would be a way. I've tried 4 signal and/or video stabilizers, but was looking for the next option. IDEAS??
