Many of the programs listed up there require a subscription or purchase in order to fully convert a video. I found a freeware program called AllToAvi but I am not sure if it has multicore support as it is only using 20% of my CPU power. Badaboom works great however there is to AVI output, is there a free program that anyone recommends that has multicore support? Badaboom also puts that ERI watermark on your videos
