I've just self installed a digital converter (motorola) between the outlet and my tv. Comcast activated it, and I programmed the tv control code. The controller only works when you stand directly in front of the box, hold it chest high, and point it at the box like a flashlight. The box seems to have a very narrow line of sight for the signal. Is this normal?, Does comcast offer a different digital converter box, perhaps not so pretty but with a wider line of sight for the signal? Thanks for any suggestions.
