Doug is correct, the dual core CPUs can be slower than single CPUs. The HD player software determines what the CPU requirement is, for example CyberLink PowerDVD HD Edition lists these CPUs:
Pentium EE - 840(3.2Ghz), 955(3.4Ghz), or faster.
Pentium D - 945(3.4Ghz), 950(3.4Ghz), 960(3.6Ghz), or faster.
Core Duo - T2500(2Ghz), T2600(2.16Ghz), T2700(2.33Ghz), or faster.
Core 2 Duo - E6300(1.8Ghz), E6400(2.13Ghz), E6600(2.4Ghz), E6700(2.66Ghz), E6800(2.93Ghz), or faster.
....plus specs for AMD CPUs. The clock speed, number of CPUs, cache size, and number of caches varies among these various CPUs. The graphics board may also have a performance requirement.
This is why you save grief by buying a laptop that the manufacturer has setup HD playback on. You will have the right hardware, the right driver software, the right player application, and all of the above configured for playback when you open the box.
