With HEAD requests? A personal spidering tool like wget could pull down
all linked videos based on content-type as specified by the server.

Well, actually, you probably shouldn't see a broken film icon because
authors should include text/html alternatives using the fallback
mechanisms provided by both <object> and <video>, and this will remain
the case until we have open container formats that are interoperable
with free and open source user agents, can serve people of differing
abilities, and have an accessibility feature-set that authors generally

In any case, how does knowing the object missing was a video not (say) a
Flash object help the end-user?
