Hi, I have a Motorola DCH3416 box and a Comcast remote with the red OK button. 90% of the day, I have absolutely no problem with my TV or remote. However, I regularly have issues at night (around the same time, interestingly). The issue is that when my Sharp Aquos TV is off, the remote clearly is able to change the channels on the cable box. When the TV is turned on, the remote works for about 3-4 seconds, but then the box stops responding to the remote signals. It's almost as if there's something about the TV being on that is interfering with the workings of the remote during the night.

Comcast, of course, is of no help in this situation (they tried to explain to me that my wireless router was disrupting the remote signal...right). I'd greatly appreciate your expert advice.

Thanks!
