Roku

If you're subscribing to a TV package, you'd get the same signal to your house in 2 ways:  cable and Internet.  Which begs the question, what exactly do you want to do?  Watch a remote TV without renting another set-top box?  There are ways around that, but what do you want to do?

I want to add tv to a room without a cable outlet and I do not want to have 50 feet of coaxial cable laying on the floors. I rent so I just cant add outlets to the house.

I am trying to access the history channel, but when I try to access it Cox is not in the drop down for service providers.

You can transmit the signal from your cable box to a remote TV with a Wireless HD Digital Kit.  There are many devices for this wireless transmission...but I'd recommend one that transmits in the 5GHz frequency to eliminate the line-of-sight requirement of the 60GHz devices.

IOGear comes highly recommended:  http://www.iogear.com/product/GW3DHDKIT/

What I like about the IOGear is you can use your Cox remote with your 2nd TV to control the set-top box in your living room.  The IOGear receiver, connected to your 2nd TV, will rely the signal from the Cox remote back to the transmitter, connected to your cable box.

Please add my request also for Cox to make the History Channel content available on Roku boxes.
