OOPS, I just noticed my error....
I had it in the wrong place - outside of the controls tag.
Sorry, what a stupidity!!!
EDIT: and of course, with the modified string (added .Drives) it now also shows in the tvguide
So, remember to modify the example in your archive.
Once again, sorry for this and thanks a lot for looking into it!
