I recently switched to D* from Dish, due to their fight in my area with Fischer Broadcasting (I'd been without ABC for 2 months). So far, I've found the D* DVR to be flashier than the Dish 622, but a heck of a lot slower. Annoyingly so at times.
The problem seems to be fixed for the Fox network, but it's still a prominent issue on ABC. What really chaps me is that this has been going on for months and it still hasn't been fixed, and of course Dish will offer us no compensation.
