Heres a thought, create and insert your logo as a 'bug' in the corner of your vids..problem solved
As a video pro, one of my biggest pet peeves are the Facebook aggregators who don't embed videos so that the original content provider gets the hits, the credit, and opportunities for more traffic; but rather rip and post as their own content the works of others. What makes it more sinister is that these aggregators are usually radio stations, other media outlets, and commercial schemers.
That said, the OP is not doing that here. From his post he's merely linking to or embedding videos provided to him or that he finds. IMHO, this it completely acceptable and even creates a distribution opportunity for those who would like it.
For video for which I want to restrict access and distribution I use Vimeo, and turn off embedding.
