Dance-Trippin TV (Not Working)

Hi,  I was trying to contact Sander1 as he seems to be the developer for this channel

I am inquiring about the status of Dance-Trippin TV. It used to work flawlessly and now every video I click on it says that the video is unavailable. did something change and if so is this something you're working on resolving? Any information would be helpful.

Thanks!
