I finally got my 622 activated and my dish upgraded to a dish1000. The installer didn't have a DPP44 swtch with him even though it was listed on the work order as "required hardware." I realize it was not actually required for the job and he simply used my existing DP34. So I complained in an e-mail to the ceo and got them to send me a 44! My question is, will this work with my existing LNB's or do I need DishProPlus LNB's to work with the new switch? I was hoping to just swap out the switch and get rid of the extra cable running to my 622.
