I can t get this software to work peroperly, when it finishes I get a windows that shows some errors then it closes, and I can t find the iso file after that.
Just about any burning software will create an ISO out of anything. If your question is that is there any program that will convert AVI to DVD compliant then the answer is yes there are all kinds of proggies that will do this also. Here is a guide to one way that works and its all free proggies http://webpages.charter.net/bacitup/TheGuides/DivXtoDVD.pdf
TFM = The FilmMachine free and awesome i use it (just like avi2dvd), has built in encoders, but i choose to use a standalone of CCE Cinema Craft Encoder not free.
