Hi, I have a standard definition Samsung DirecTv Tivo receiver (series 2, I believe). It works great. I am upgrading my service to HD and I am adding a DirecTv HD DVR. That upgrade includes upgrading my dish from a dual lnb to the "slim dish (5 lnb)", sorry if I have the terms confused. My question is, will my existing Samsung DirecTv Tivo continue to work with this upgrade? I really don't want to get rid of it. The DirecTv customer service person says it will but I would like confirmation from someone who may have a similar setup.
