Need help adding things to "watch later"

[So Fresh]

When I browse to my DLNA shared "content" and select a video and put it into the queue, it shows up but tells me that this "video is currently unavailable", but I can play it the regular way with drilling down 85 levels to the file.

So now my queue is filled with 100+ things I can't watch, is there any way to fix this or if not, mass delete things from my queue?

I also can't mark you tube vids as watch later.
