Video capature program that utilizies quad core

Hello



I have a computer with a Q6600 processor in it. I use my computer to convert vhs tapes to dvd and it takes a lot of power to encode the video after capturing it. When i had my old pentium 4 computer i used a nero capture program but it was pretty old program so i'm assuming it cant utilize my Q6600. What programs are out there that would let me complete this task while using all of my processor. I dont mind paying for the program.

Thanks
