I know similar questions have been asked, and I've gone through various postings but since many setups vary, I figured I'd be more specific to my situation. So, here it goes: About a year ago I upgraded to HD. They installed a Slimline (5 LNB) dish and ran one extra cable to my living room. (In hind sight, I wish I had them run a fourth cable from the dish but I digress). So my current setup is: Slimline dish > 3 cables out 2 cables are running to my HR20-700 in living room. 1 cable is running to my HR23-700 in bedroom. When HD first installed, I only had an SD legacy tuner in the bedroom which is why only one cable. The issue: In the near future, I would like to run a second cable to the HR23 so I can utilize both tuners. BUT a little further down the road I might want to add one legacy SD tuner and one more HD DVR (or just two HD DVRs). So this means that I may eventually need up to 8 coax cables (definitely no more... not in this house anyway). So it would seem that my requirements are: 1) I need a fourth cable coming from my dish first of all. Now, can I do this myself? Is it hard? Will it require dismantling the dish and/or re-aiming? Unfortunately it is kind of high up and in an awkward position. 2) I have concluded that I either need a WB68 multi-switch *OR* a SWM-8. It seems that SWM is probably the way to go, but I seem to have read about people having problems with SWM setups. It seems like lots of people use both but it doesn't seem necessary to me for my situation. Also, can either option support at least one legacy SD receiver? Ideally I would like to do this myself. I have no doubt that I CAN do it myself. Really the biggest problem that I know I will have is running that last cable from the dish. I wouldn't really have a problem paying an installer to do it but I will likely be having a new roof put on my house within a year or so, which of course is going to cost me to have DirecTV remove and replace/re-aim the dish when the new roof is installed. I actually asked the installer to mount the dish on the side of the house when I upgraded to HD and he said it was too heavy. Oh well. Any advice would be welcome! Thanks!
