I used to run a Intel E7500 duo2core cpu and ran Mezzmo and was able to play all my large blu ray rips onto my Sony BDP s480 with ease and never had this issue. I gave that computer away and built and AMD 6 core rig and for some reason I cannot watch the same movies like I used to? Im not sure what version of Mezzmo was on the old computer but for this on im running the latest one 2.6.7.0 . Im using Sony BDP HT SMP profile. Is anyone else running similar CPU having same issues?
