Recently I got these, AVI, MP4, M4V, MKV files. Now I want to burn them to a DVD. Which program should I use?
Try video converter ultimate. It is strongly recommended by M2mate.
Try Nero Media Suite
Here is a nice article that covers most of the DVD burning issues http://www.wikihow.com/Burn-a-DVD
Try Total Movie Converter by CoolUtils
Roxio Toast is better as it can also burn iMovie projects.
Free one is Burn software
AVS video converter can create DVDs and it is extremely easy to use
Here's a step by step on the Apple Support Community Site:
If you want to burn them to a DVD just as data (like a backup) any program will do.
If you want to burn them as Video-DVD (MPEG2) e.g. for playback on a DVD player which doesn't support all those codecs I believe DVD Flick is a good option.
