This thread is supposed to be about the ViP 211, not the Hopper. The OP evidently lost some events from their EHD and believe Dish made changes to the 211 firmware that caused that to happen. They don't want to upgrade their hardware as they don't want to be tied to a 2-year commitment to Dish Network. But buying a Wally to replace their 211 should be a fairly easy process and no commitment necessary if you own the equipment.
So far, Dish hasn't emailed us anything about our 211k receivers, so they aren't actively trying to get rid of them.
