call me an idiot but i tried to spare myself from asking this here by googling it...but that failed. What do these processors do? what hooks up to what to get it to work? do you need one for a projector? does everything you want to come out of your projector (tv, vcr, dvd etc) go into the processor and then the processor goes into the projector? Do these things naturally cost alot, or does it depend on the company, or what projector your usin or what.
