I met the same problem with xilisoft dvd creator. when i downloaded v3.0, everything works fine. the software works much faster with higher output quality. I like it.

It make my life much easier and the things faster. Here is something about v3.0:
* Trim Video - You could trim any segments of a video to burn to DVD.
* Support Video Miniature - You can set any segment or frame of a title as the title's video miniature in menu.
* Menu Editing - So many brilliant DVD menus to convert MPEG to DVD; Support selecting background music for a menu; Support selecting background image for a menu; Support editing the title text of a menu, and change the color of the text;
* Support preview - Support preview videos before creating DVD.
* Support setting actions after done- You can set the actions after finishing creating DVD, including "Shut Down", "Hibernate", "No Action", "Standby", "Close Application".
* Support directly playing main movie by skipping menu.
* Support several types of DVD disc including D5, D9 now.

uhmmm, the interface is nice too.
