I have been using ConvertXtoDVD 3 for the past few weeks and it has been working great. At least, for my downloaded movies. However, when I rip my old DVDs onto my computer and try and convert them, it doesn’t work. I get everything ready, and when I press “Convert” it shows the progress bar, and nothing else happens. No preview, no progression, nothing. The video is AVI format, so I don’t see what the problem is.
