In the past few weeks my local CBS has taken about a 30 point dip in signal strength down to 61. I have a neighbor that has the Tivo HD unit from DirecTV and still gets about 96 signal strength. I have called the local station and they gave some lame excuse about squirrels chewing on cable lines and interfering with the transmission in my neighborhood. Has anyone experienced a signal loss with their 942? Trying to rule out possible software release that could have caused this. My other local channels were never that strong, but their reception does not seem to be affected.
