We have an older, 2004 I think model Hr 10-250 Hughes DVR dual tuner running Directv off a 3 lbn oval dish. The unit is starting to reboot several times a day and I'm not sure if it is just starting to go or the mysterious reboot problem. I would like to keep everything the same (no HD) with a new unit however it looks like it will have to be an HD receiver. Questions: Would a directv Tivo THR22 work off my existing 3 LBN dish, (no HD)? Where do I buy it, from Directv or someone like Weak Knees and I guess there are others selling them? I read about the 2006 lease thing with Directv, who owns the unit? How can it be that I buy it yet lease it? If it will work on my dish is it an ok receiver? We have had Directv in our homes for longer than I can remember but I have lost what's going on with the latest technology as nothing has ever need to be changed.
