Has anyone used a "Video Sender" ?

I have the Terk Leap Frog device that sends Audio and Video and allows control of the source components through an IR repeater. Works great as long as you don't have a 2.4ghz phone or a wireless network router. These both interfere with the signal transfer. I was able to switch the channel on both the LF and the router with decent results, yet there is still some interference.

Yes, they are useful devices. (I have used them with good results) They will not allow you to watch a DIFFERENT cable channel at the 2nd TVs location, (for this you would need a 2nd cable box)

Some units allow you to control the cable box from the 2nd TVs location, (recommended) and others will not. There are many to choose from. Here's a link to one I used.
