Pushed my 5 HR20-700 from 0x059E to 0x05CD over the weekend. What a difference. All the menus are now fast. The DVRs were unbearable to use before. I don't have any remote button issues or resolution problems. I did notice that for the first few days when I pushed menu, My Directv did not show any shows and loaded faster. Now I get recommended shows and menu and list load 1 or 2 sec slower than before. Overall, the DVRs are usable again.
