Don't do this for your Product Hunt launch!

I just launched a product on Product Hunt (for the first time), and it asked for a Youtube URL. I scrambled to upload a product video to Youtube, then pasted the URL into Product Hunt.

It's probably because it was newly uploaded, but Product Hunt was unable to show the video at all (I could see it on YouTube just fine).

Now the lightbox my Product Hunt page is showing a YouTube video that would not play :(
