I am considering purchasing a Slingbox M1 as I travel frequently for work. My plan is to order a second cable box from TWC and use it solely for the Slingbox so that I don't have to worry about changing the channel while my wife is at home watching tv (or vice versa). Since this box would only be used for connecting the M1, I don't plan on connecting a tv to it. Will there be any issues with not connecting a tv? I don't imagine there would be, but wanted to be sure before I purchase.
