Ok this is the only thing i can come up with when ever i do a movie i encode and burn in about 35-40mins, now my mate has the exact same setup except with an extra gig of ram and a 7800gt, he gets the same results as me. Now my Bro-in-law has a Dell P4 2.8 HT with 512mb and onboard video and encodes and burns movies in like 25 mins. Ill totally accept the answer that Cloen DVd uses HT, but its not mentioned on slysofts website, yes i have my Drives DMA enabled and on all situations all the lastest versions of Clone DVD and AnyDVD have been used.
I have a Dell laptop with 1.6 GHz, 2 GB DDR2 RAM, 2 external HDs via USB, and 3 burners via USB and Firewire and I usually get times around 25 min. as well. I recently upgraded from 1 GB RAM, and although I can see the difference in multitasking, my transcoding/encoding times didn't improve significantly. I opened as many as 30 apps at once with no slow-downs or hangs, but I don't multitask while burning and encoding anyway. However, I did rip 3 movies simultaneously (each to a diff HD). Getting back on topic, I don't think HT has a effect as I don't have it. EDIT: The reason I mentioned the USB peripherals is because an internal HD will transfer data quicker than a USB external. Hence, another variable to slow my times.
