I have 1 hd tv and two regular tvs along with a pc right now. I want to add a laptop and maybe a game system to the mix too, but am concerned about the about of feeds I can use at one time. I can't seem to get any answers when I call or chat with at&T...Do you have any thoughtson the streams? I want to make sure that if I am recording shows that using the internet or game system won't prevent my show from recording.
