Most cable company tech support is worthless. You first need to determine if the ir port on the back of the box was activated by your cable company is active. If it is, a simple 3.5mm to ir receiver cable with the right frequency is all you need. If its not active, then you need a little more cumbersome unit that has one lead to a receiver to get your remote signal, and another lead that essentially tapes to the front of you ir reveiver on the cable box. Like this The two leads then connect to a processor box that sends the signals through. In either case, the receiver side of the cables needs to be outside of your closet walls for you to point your remote at it.

Get a Xantech DL85K kit and that will solve your issues. I use 4 of them and all cable boxes are hidden. Your closet needs 2 outlets to power box and repeater. Also you would need an ultra slim HDMI cable to go from closet to tv. That would mean you power tv from existing outlet and feed tv with 2 wires from closet. Wires from box are easily hidden and tv install is now just a monitor.

If your cable service also provides streaming via your internet service you use WiFi, and you are only wanting to get TV, try something like a ROKU stick. The newest TVs usually have a USB port and the stick gets power from it. The stick is then connected to an HDMI port on the TV. Doing this allowed me to get rid of a digital adapter which still required a cable connection.

Salti: An RF remote will certainly work and be more reliable, but they are considerably more expensive and require more setup than just using an ir repeater like I mentioned alone. Most harmony remotes are IR, not RF. Not sure why anyone would want to do that with just a tv and cable box in the kitchen? She already has a remote that does what she needs, just needs to get that signal from the tv area to inside a closet.

cobalt: THE DL85k is nice. I have one too, but I think it's overkill for her needs unless she intends to add more items in the future.

Thanks for your replies. Yes, there is a coax jack on the backsplash behind the TV, and the entrance closet is on the other side of that wall. So it's only a matter of switching the coax jack over to the closet side, and adding an HDMI cable between former coax jack on the kitchen side and the closet. There is a light in the closet so I would just replace the switch with a combination switch/receptacle.

I have found many IR repeaters on Amazon and other sites, including the Xantech DL85K, but most of them have many bad reviews stating they don't work with Cisco boxes, which is all Videotron provides. Can somebody confirm to me if they would work with the Cisco 4250HD?
