I would like to recommend a video convert tool to you. Its functions are great. It can convert DVD to VCD, dvd to gif, avi to mpeg, dvd copy, mpeg merge and separate, avi making and build screensavers. It also can split, merge multimedia files. And it can select frame from the start point to the end point. You will find it's wonderful. I have found it for a long time. And I found it really do perfectly.
