Dear All, Forgive my ignorance... After several failed attempts to obtain a second signal, supplied to my PIP ready Samsung 50", and for the purpose of PIP, I have discovered that I am in need of a second DT receiver, and it the only way I can achieve this objective. My questions are; Can I simply purchase a used DT receiver (found a used model 'gaebo', does not come with any card), connect it directly to the dish, then to the receiver and my TV and be done with it, or do I also need a card? If I do need a card do I have to 'activate it through DT? And, where do I get one? Your direction is much appreciated.
