Yep... RF routing has to be done... The MX stuff works well when you can get around the RF problems, but just go straight to the MRF-300 and this will elimainated 95% of RF issues with the MX products...You have to be slick in the setup, and of course you customer will have to have some savvy, but it is easily done. I did the same deal with a office housing a 60" Pioneer Elite plasma, and (2) 37" Sharp Aquos LCD. Worked great..
