DVD Duplication Information

I have home movies in various formats and some DVD's and CD's and I would like the ability to take individual scenes from multiple source files and put them onto a single DVD. I have tried using my computer and software but the "rendering" process is simply too time consuming for what I am trying to do. Is there specific equipment I can buy that will do this? I am willing to spend some money. Thanks.
