Has anyone here contacted Fengtao about this problem? I only use the free DVDFab ripper myself with the latest 5.0.2.0 beta. The program has been buggy at times, but the latest seems ok except for the lingering GUI bugs from earlier versions.

Now that Fengtao has Linux with Wine listed as a supported OS he may want to make sure people can get there License to work.
