I noticed when trying to convert back to
DVD it got to 28 percent and stopped. I am trying again just in case it is "one of those things". Also noticed sometimes the preview is black and my PC needs to be reset to work again. Thirdly it seems to crash WMP when trying to use the slider to move along the video.
Apart from these little niggles, the software is amazing, converted a 8gb DVD down to 1.1gb with quality much better then that of SVCD (in my opinion).
