A colleague has a blogspot.com site. She took her video embed code from you tube, copy and paste and bam! nothing... (from her mac)... same day, same time on my pc we did it and all worked fine for her.
In the past I have had issues with the embed code from YouTube in a Blogger post. It is sometimes missing the or HTML codes from the end of the embed and Blogger will not show the EMBED. You can add these links manually if needed. Watch for errors when you publish the post.
Also, if you paste in the EMBED code when you in the Compose tab and not the HTML tab, it often breaks the EMBED HTML codes and turns them into simple text.
If you have more info, pass it along and I will offer up some more ideas.
Cool. Let me know and we can try and duplicate it. Usually I find it was just a misplaced Copy and Paste or something simple. YouTube is pretty darn reliable for embeds.
I advised and invited her (Robin) to join new media interchange, and looks like she will be joining.
So, if she's not resolved in, she'll be writing in directly.
Thanks!
