I used the dlls of the guide: in the last few days he did not let me download them and so I used those dates from Primera, but they are a later version and therefore we see that they do not go well with imgburn.
For the second question, I do not want to make them convert files. I meant that I have a DVD with 4-5 movies in mp4 or avi and I wanted to copy the files and not create the ISO: is it possible?
