I have just read in the news that the EU agreed on a new directive to regulate copyrights of video sharing sites, and it means bad for us music collectors. The sites will have to filter more what is uploaded. I suggest you to start downloading as much content as you can because soon even more videos can go missing.
If you want to upload in the future, but Youtube rejects the upload, try Vimeo or 4Shared. I think the latter one still has quite loose policies. Not sure about Vimeo.
