It sound like an easy decision, stay with Adelphia.
The waiver process for analog signals was abused by the satellite companies and their subscribers. Congress is now forcing E* and D* to carry the local channels and not cheap out by using the waiver excuse.
That may be the only choice if I don't get the results that I am looking for.I did enjoy the PQ of D*,although Adelphia is not bad. They are quite a bit more expensive than the services we had in Alexandria,with D*for viewing services and Speakeasy for our ISP and VOIP(running 2 servers) our total was only 140.00 per month. Adelphia does not allow servers unless it is a business account,no VOIP unless it is an add on such Vonage/Sunrocket etc with less options we are over 200.00 per month for viewing only--but as you said it my be the only reasonable choice for stable service
