Sorry for the delay in responding viper... hadn't had much time lately.
I'm not sure what speed you refer to stating '1.8'. I get very different results in the Speed entry on the CCE status window. Anywhere from 0.4-1.1 seems to depend on content and not so much resolution and Q-factor (both monitored with 352x288 and 720x576 res. with Q between 1 and 40).
I looked into OC'ing once again, and found that I was already running at 5%. I stepped down from 10% when CCE hang arised. I can't seem to find where to control FSB as you did?!? I am also low on fans - only fans are in PSU and in front of cabinet (very hot air flow through PSU

)
Finally, I looked for the libmmd.dll, but didn't find it anywhere on my system. I DO run HT though! (two CPU's in task manager).
