Returned to DTV after a few years. Had the genie installed today with 3 additional clients. The installer told me a few things and one of which was false so figured I'd ask here. He mentioned that if I'm watching live tv on all 3 clients and the sever that I couldn't record more then 1 show. If I was watching 2 clients live tv I could only record 3 shows at a time. Is this true? He also said I couldn't rewind live tv in the other rooms but I showed hom I could. Is there normally a 3-5 second delay switching channels on the clients?
