I am a tech for Comcast. Call customer service and ask for the X1 box. It has 6 tuners 3 of which are active right now to record 3 shows at once. All 6 will be activated eventually.
Currently, the X1 box only allows 2 shows to be recorded at the same time, but a third show can be watched live. See »Re: [X1] Xfinity TV on X1 Platform and X1 Remote Control App!
