Can someone explain the Receiver Rev and Rom versions? I am lookig at upgrading to a 721 and I found one with a Rev of A21 and ROM 10. What is the Rev and Rom and Should I stay away from them or are they ok? I guess, does these mean anything? One is being advertised as eaisly programable? What does that mean? Is that an upgrade and how do I do it? Does the 721 have a smart card built in? What is a blue card? I have seen the 721 advertised with out card. Will my card from my model 5000 receiver (the one I want to upgrade) work in the 721? Where can I purchase just a card and how much should I expect to pay for a card? Can a 721 be activated on a current customer (since 1997) account?
Sorry for all the questions, but I am not educated on this. Any thoughts or questions, please let me know.
Thanks
