Apparently, LiveJournal [1] filters out embedded material (using the <OBJECT> and <EMBED> tags) and drops everything else past that when reading syndicated feeds.
Also, the use of the <EMBED> violates the HTML (Hyptertext Markup Language) 4.01 Transitional standard, but without the <EMBED> tag, the video isn't actually embedded.
Sigh.
So I just removed the embedded video and provided a link to it.
And people who read me exclusively through LiveJournal [2] will now know what I'm talking about.
