I know this is a little old, but here are the supported CPU's for the Zino HD 400: AMD's Athlon 64 2650e/2850e or Athlon 64 X2 3250e/6850e The 3250e and 6850e are dual core and give a better experience than the single core 2650e/2850e Another addition you may want to consider is the Broadcom Crystal HD BCM70015 which will improve HD support. Also using Windows Media Player Classic helps with playing blue-ray files
