YouTube code not accepted

[Paul R Miller]

I recently posted a project in the appropriate forum along with an animated video of the piece (a marquetry box) turning itself inside out.
The YouTube ID code is X****LjyH9g. This ID is in both the share code and the embed code and which ever I use the four lower case letters are replaced by asterisks rendering the code invalid.

Here's the strange part. When I typed the above code, I typed four lower case letters where you see the asterisks. I can't get the site to accept these letters, even when I type them as a separate word. I'll type them again: **** I did not type asterisks. Trying again as separate letters this time with spaces they are: b o r k
If these letters replace the asterisks, the link works but I can find no way to get the site to accept them.

BTW, I have used the code elsewhere and it works fine. It's just here.

Any ideas? It's a cool little animation, too bad you can't see it.
