How do you burn downloaded movies onto disks?

You will need some burning software to start with. I use ConvertXtoDVD which has worked really well but others have also said that Nero is good. You may also need what is called a CODEC pack. These are free and the one I use is K-Lite.

To burn to DVD it is a good idea to have burning software that you can choose the resolution of the DVD you are going to burn to otherwise you might end up with a distorted image. In all it is a really simple process once you get the hang of it. Hope this helps
