Something I found whilst at PLASA and thought it may be useful to share.
If you have channels (or addresses) parked and then load another show without having unparked said channels, those channels are remain parked but are not displayed in the new shows Park page. I.e. the channels are still live but are not displayed.
To rid yourself of those pesky channels - dive into Park, and park the channels, then unpark them again.
(I've typed the words 'channels' and 'Park' far too many times in this post!)
