My TV is possesed

JP and I have enjoyed cable for many years. Recently our cable box kind of exploded and stopped working. It was really tragic actually. JP called the cable company and they wouldn't send us a new box until they tried to fix it over the phone. So after a 45 minute phone conversation, our cable box was supposedly fixed. Well, after two days come to find out it was not fixed. So again JP calls and is on the phone for another 45 minutes. This time they agreed to send a new box. So now we are enjoying our cable again. The only problem now is someone around us has cable through the same company we do and somehow their remote changes the channel on our tv. This gets really frustrating! I will be relaxing, watching tv and next thing I know the channel changes. I have figured out that it is a guy because it always changes to baseball or nascar or some other manly show. Sometimes we play a game where for about 20 minutes we are switching channels back and forth. Then it stops. I need to call the cable company and see what we can do about it because it is annoying!
