Yeah, I ended up just paying the $10 extra per box and getting the smaller box that can still access the DVR (if you have Comcast or something similar). It's just easier than trying to split it and it'll enable multiple games to be watched if you have a party. Just made sure to run the Coax all over. Ethernet to the big screen that has all the gaming systems, the other tvs are fine connected via wifi.

Agree with meSz. Run the cable. If it's not going to be used often, it's easy enough just to grab a box from inside the house, and hook it up for the night of a party or something. Better to have too many options than not enough. And speaking as someone who cut about a dozen holes in the walls and ceilings to run coax where I wanted it, run everything you can think of before the drywall goes up. Better to leave it unused than to decide you want it later and have to add it in.

Your space is looking amazing by the way. Can't wait to see it completed!
