Hi, I'm interested in upgrading to the Genie, but after reading several threads here, I have a couple of questions I would like to have answered to help me determine if I should go down the upgrade path and, if I do, what to expect. First, my setup: Living Room - HR24-500 with 2TB WD housed in an MX-1. TV is a Samsung Plasma 3D HD TV and I use the HDMI connection. Master Bedroom - HR20-700 with 2TB WD housed in an MX-1. TV is a Samsung LCD HD TV and I use the HDMI connection. Both are connected to the internet via DECA and I have Whole Home. I also have a Hauppage, so I don't mind recording off conent from the HR20 onto my NAS and then retiring the HR20. I have a lot of unwatched movies on the HR24 and only if there is significant benefit of retiring it would I go through the effort of also recording its content onto my NAS. So, at minimum, I'm looking to get a Genie for the Living Room and then move the HR24 into my Master Bedroom, after first retiring the HR20. So here are my questions: 1) Will new cabling required or will it be "plug and play?" The cables from my Master Bedroom currently run under the house to the Living Room, so I need to know if this will have to be re-done. 2) Do I lose any functionality by also retiring the HR24 and getting a C31 for the Master Bedroom instead? I just need to ensure that I continue to get the exact same (or more) functionality that I currently have by having two independent DVRs. 3) I read here that the Sans Digital MR2UT+B (http://www.sansdigital.com/mobileraid/mr2utplusb.html) works with the Genie so I'm also interested in getting it. However, what I couldn't clearly determine was the exact model of WD 3TB drives that would work in it. I'll be running it RAID1. If you have an exact Amazon link or equivalent, I'd appreciate it. Thanks!
