Before these threads, "legacy" referred to non-DishPro receivers with model numbers in the 1000's. In addition to those, the 301 and the 50x series PVRs can't demodulate 8PSK, so they're definitely on the chopping block.
All later receivers can do 8PSK so they should be good to go
for awhile. Next to go will be the SD receivers that can't decompress mpeg4 videos. The 411, 922, and all the VIP receivers are fairly future-proof and can handle all signals that the Hopper can with the exception of 3D.
Calling VIP receivers "legacy" violates my tender sensibilities.
