I use burn 4 free but I somehow managed to mess it up and so I downloaded it again, no problem so far but it seems to be a much more sophisicated prog than the original one and it looks very complicated. I can still burn CD's OK but there is reference to burning DVD on it but I dont know how to proceed.
As for burning DVD. I'd like to recommend convertxtodvd, it's the best dvd burning software I have ever tried. I always use it to burn DVD for playback on my TV, it's easy to use and works pretty well for me, the burning speed is reaslly fast, if you are interested in it, here is a step by step guide about how to use it http://www.reviewstown.com/how-to-burn-avi-divx-movie-to-playable-dvd.html
