Cannot download xhamster videos

I am unable to download from www.xhamster.com What happens is that the website sends a substitute video instead of the requested video. Ive tried this for some months and is always the case (with an occasional exception).I have no problem downloading from any of a dozen other websites but xhamster is always a problem. Here are a few samples:
https://xhamster.com/videos/corinne-meehan-ripped-muscle-chick-8807597
https://xhamster.com/videos/thick-muscular-brazilian-babe-9445769
what is being substituted is some other file when I try to download, not the file I was viewing Thank you..
