I want the Voom hd channels but Dish won't put them on my leased 942, which I got it in may of 2005. So if I have them install a 211 would they activate a new 942 that I purchased to replace the leased one? I want to at least use the 942 to record OTA programs. And what type of switch would I need to run both HD receivers in HT along with a 311 in the kitchen?
