How did you locate the "original" address?
I didn't really do anything on purpose. When I hit your link, I got taken here:
https://youtube.com/watch?v=hk3KfGJbO2U ... u.be&t=102
So I already "had" the link, just edited out the "&feature" part.
The other way to look at it is, every YouTube vid has a unique id. The id for this vid is in both your link and mine.
Your link was of the form:
IGX board software recognizes this form:
So you could just routinely take the vid id and change it into that form before posting.
Only thing, I guess the embedding doesn't recognize the "time" piece of the link — won't start at a section, it embeds right at the beginning.
