Hi all, My current setup is a 6000 receiving 110, 109(dish500 dual LNB) and 61.5 and a 4900 that only gets 110 and 109. I have a sw21 setup. Here is my plan. I will have an installer help me. Switch out the dual LNB for a quad. switch the sw21 for a sw64. I will have the 921 and 6000 seeing 110/109/61.5 and keep the 4900 w/110/109. Am I ok here? Also, I read about this bug report: http://www.dbstalk.com/showthread.php?t=22162 where james made this statement: 'Ok, Development here, now it won't book again, Dish told me that an e-mail went out to all retailers today that said that you HAVE to download the first software upgrade from a twin (Before going to anything non dishpro) and if the customer doesn't have a twin, that they are supposed to do it in shop before it is installed. They said my software may have gotten messed up and to "Return it to my retailer"' None of the equipment I am going to use are dishpro. is there a sequence of events I should follow when the wires are run and I first turn on the 921? Should it be power on->software dl->check sw->all is well or checksw then dl??? I do not want to mess this thing up! Thanks VERY much in advance. FREAK!
