I have searched everywhere for a fix to the slow hr22 problem. I have also tried everything, Manual Reset, 0-2-4-6-8 at first blue screen, Reformatting the harddrive, turning native off, turning all but one resolution off, you name it and nothing has worked.
What did work for my HR22-100 was to tell it to hide all HD channels (I know that defeats its purpose). That put me back to where I was before upgrading my dish to a SLIMLINE 5S or S5.
By the way, that is when my troubles began, upgrading my dish get HD channels,

. I have ordered an HR24 and we will then see what happens. I think some HR22's cannot handle the HD signal from the SLIMLINE. I have the shiny finish one. There is an opaque finish one out there, or so I hear. Or the cable run is too long. I live in a condo with about 200 feet of cable run from the roof.
I hope this helps someone like me out there that could not find an answer.
