I haven't been getting any responses to my other questions on here, but thought I'd try again on this question. I got my Ultimate set up & thought it was working fine. All of a sudden today, it starts changing channels & also just a little earlier I came back into the room & found that my TV had been turned off. I've looked on Google to see if there are any known issues with anything related to its RF signals or anything that would cause this. Does anyone have any idea as to what could be causing this?

Thanks
