@hansel75: Many thanks for your explain. Now i clearly understand what's your issue but not why you have it.
Have you try this X-bench cli command?
The resetxset command was created to reset all the previous setup to have a clean new install. You must set and scan your hd again after this command.
If you've already try this can you please send me all the files that you have in your xbench/prefs/ drawer ?
Thanks for your help to debug xbench
