How to delete windows shared folders on wdtv - they do not disappear :-(

hello forum friends,
I experiment with my new WDTV live just for my extensive photo collection on your PC. the media library, I did not like so well. so I changed it. windows with shared folders on my old windows xp computer The shares will be displayed on the WDTV live properly. Then I deleted the shared folders on the computer again. but they will still appear on the wd tv :-(. they are indeed empty, but take unnecessary space on the screen away. someone plant a tip as I delete the folder again without the reset?
greetings from Germany

Have you tried turning the media library off and then turning that on again.
