We recently noticed a change in our picture quality on our non HD channels. Has Verizon changed their non HD channels to HD channnels? When you watch movies its almost like your watching a low budget movie. No settings were changed on our set and we have anon HD box connected to this set. Has the service in our area changed in any way? We are located in Marlton, NJ. Please help as we are trying to determine if this is a problem with our set. Thanks!
