[X1-X2] Question about X1 DVR set up

Im thinking about ditching Dish and going with a Comcast double play to save some money every month. Anyhow, I have 3 tv's I need hooked up, but only two with DVR. So, I was going to order the digital box for $2.99/mo for the simple tv, but I want DVR access for the other 2. So, I selected the X1 HD DVR, but it wouldnt let me select a second. It only allowed me to select the regular X1 HD platform. Will the X1 HD platform be able to access recordings on the X1 HD DVR, similar to my current Dish Hopper set up? Thanks! Quinn
