CloneDVDmobile doesn't seem to work with my Vista Ultimate although all other Slysoft products do. As soon as I specify a source location, either by typing an address or pressing the "Browse" button, I see a dialog box which says "Application has stopped working" with an "APPCRASH" event. The problem occurs for all output formats and seems to be directly related to the search for the source address. I tried "XP Compatibility" mode, running as Administrator, and if fact, even turning off UAC. None of these options correct the problem. As I said, all the other Slysoft products work just fine with Vista.
