I work in the hospitality industry and those recievers are some of the equipment I order and work with. Are those VIP (222, 311 etc) recievers? The old recievers I believe need new smartcards while the newere ones are built in into them that can be updated remotely.

Send me a pm. If you can send me the smart card and reciever numbers I can probably target those for the updates at work. You will have to wait until tuesday though. BTW, i don't work for dish.
