Dual Core Support in DVD-RB Pro??

Is there any support for Dual Core CPU's?? I have a Athlon X2 4400+ @2500Mhz and with the old Versoin of DVD-RB I had a Speed of about 6 and now I bought the Pro Version and have only Speed from about 3 !!?? Cu Penecho

Something else has changed. The pro version isn't slower or different in the way it uses processors. What encoder are you using?

Same as before, CCE 2.67 Cu Penecho

Have you changed any of the O/S or BIOS hyperthreading options -- that seems to be a more likely candidate. I'd guess that you were only using one processor during encode now.
