A couple of questions from a video hoarder concerning a possible move from a 722 to a Hopper Duo. Apparently I can get this upgrade with little or no cost from what I hear. Would they just send me the hopper? I was told I can still keep the 722, which is nearly full of saved programs. I also have a couple of external hard drives full of programming. Will my 722 saved programming be lost after I switch, or would it still be there if I just wanted to plug it back in and watch those? I'm pretty sure the ext hard drives would still be okay, but what about the programming on the 722 hard drive? Thanks for any help!
