      If I have 2 TV's can I get away with just one cable box? Sorry, I'm new to cable service and am going to order this next week.

      It depends on your cable provider, your TV set, your package, and what you want to see on that second set.

      You may be able to connect the second TV without a box if it's newer (digital) and has a Clear QAM tuner, and your provider allows it. It will not get you premium channels, but in general those channels that are in the first 100 or so. Some cable companies will give you a "free" box (As in, they own it but you pay no fee) that allows you to get those basic channels on an older analog TV.

      I would discuss it with your installer when he comes.

    You can do this if you don't mind watching only one TV at a time or watching the same channel on two TVs.

    Easiest way is to simply put the box in one room and connect the A/V out to the TV in that room then run a coax cable from the "RF out" port on the cable box to the TV in the other room. Alternatively you can get a splitter and split the RF out signal between the two TVs. You will need an RF remote control such as the Harmony 890 with the RF to IR extender because the box will be in another room. You won't get HD with this setup at all. In fact, the analog outputs may be disabled when you plug in an HDMI cable so this won't work even for HD on one TV unless you use component cables. You can get a HDMI switch and use HDMI cables for both sets and that will work. One of the HDMI cables will have to be long to reach the other set.

    Another way is if you have active outlets in both rooms just move the box with you from room to room. The disadvantage of this is that you have to plug/unplug and carry the box with you, as well as wait for it to boot (minutes). If you're using a DVR you will have to either wait until no shows are recording or you'll end up with partially recorded shows. I don't think the cable company will like this as technically you're not supposed to move the box on your own.

    So yes it CAN be done but no solution is going to be as elegant as having two boxes.

    With Comcast, you have to have one regular set box. If you only want basic channels through 99 in other rooms, they will give you a free box that you do need to have but again, doesn't cost anything. This is a super tiny box, smaller than most OTA converter boxes even. If you want channels 100 and over, you will need a regular set top box.

    Yes you can do that. To connect multiple TVs to one cable box, you need have splitter to split cable signals. There is also a switch box to do that. But it is better to use splitter as they are very cheap and easily available in the market. Switch box is expensive and it comes with lots of functionality. So, some of the functions remain unused.
    Only problem will be that you cannot watch two different channels in two TVs. One cable box will produce only one channel. You can watch the same channel in multiple TVs in different rooms.
