OK i decided to make this a sticky here that a lot of people recently have had trouble with CCE locking up and freezing when encoding ...
A recent discovery by myself was that it was caused in my case and a few others found to be problematic ATI CATALYST™ drivers to be at fault
A change/upgrade or rollback/downgrade of these drivers has resolved the CCE freeze problems in several cases
So to sum up IF you have an ATI RADEON SERIES of card in your system and are having lockups with CCE then try downgrading or upgrading the CATALYST™ drivers and see if this resolves the LOCKUPS
hope this helps some people with their encoding problems
