Longtime lurker (like, 7 years), first time poster ... I am very ready to jump into HD. I want to upgrade to a 622/722 from my 501 (so long free DVR ), but I had some questions after doing much research. I'm still using my original Dish 500 dish. It is my understanding that, to access all HD programming, I need to see 110, 119, and 129(or 61.5). I can do this with either a 1000.2 or a second dish. I live in a small group of apartment units owned by a local couple. They are great landlords, even installing my dish on the roof when I moved in and drilling holes to run the cable into my unit. However, (newsflash) it is winter in north Idaho right now, and I'd feel bad asking him to get on a ladder to get on the roof in the cold/snow/freezing rain. My plan is this: After poking around the EKB, I discovered that many of the HD channels I would watch are actually on 110--TNT HD, DishHD,HD Theater, HDNet, HDNet Movies, ESPN-HD, AND my HD locals out of Spokane (PBS is the only HD OTA I can get). Can I just swap out receivers and enjoy the above HD channels until the weather gets better and my landlord can more easily get up on our roof? Are there any potential switch issues? I know I wouldn't be able to fully take advantage of the multiple tuner capabilities (e.g. recording 2 HD's simultaneously) with my current set up of single cables from 119/110 into a SW21, but would I still be able to view HD channels? Also, seems like replacing my current dish with a single 1000.2 would be the simplest and easiest thing to do. But someone locally told me that they only do 2 dish installs b/c the bigger dish was "being phased out." Is that true? Thanks in advance. I love "wasting" a few hours on here every once in a while to stay up to date on things. I'd like to think I will someday know enough to post more than once every 7 years, but I don't see that happening!
