I have read on here that the primier is slow becasue of a issue that forced them to disable one of the CPU's cores. I also recall discussion that this would be fixed at some time in the future. Still waiting on that.... Anyway, does anyone know the technical reason that the HD interface is so slow even with a single core ? I mean, even with the video window closed, there is a considerable delay when simply going from show to show in my whats whats playing list. I can understand that things may be sluggish due to a single core, but I would think simply navigating within the now playing list shouldnt be so slow. Does anyong know why this is so slow even with a single core ? I wouldnt think that navigating the now playing list would be much different in HD or SD mode.
