AVStoDVD
AVStoDVD enables you to convert various AVI and MPEG formats to DVD compliant streams and burn them to disc, save them as DVD folder structure or store them in ISO format. The program takes advantage of several Open Source applications that come included with the installer (AviSynth, ImgBurn, QuEnc/HCenc/ReJig/FFmpeg...) and are seamlessly integrated with AVStoDVD.
