Default MP4 to DVD converter

I've recordered some 1080p HD videos on my phone and have transfered them to my computer. What software do you recommend to convert them to DVD? I tried some that came with my computer but for some reason they don't play back smoothly. (I have 6gb ram and a quad core computer so I think thats not the issue).
