Can't copy downloaded files

I joined a fansub to get video files, anime, before they are liscensed, but they won’t copy! They don’t say if they are .mkv or what. DVD Santa sees them but closes. Are they being blocked in some fasion I don’t knwo of?
Also, if you see this post elsewhere, please excuse me, as I couldn’t find it and thought it didn’t post.
Thanks:)
