If the particular codec is not supported, it displays the fallback content instead. If you want to offer multiple formats to cater to disparate UAs, give <video> some <source> children rather than @src. It will try each <source> in turn until it finds one it can play. (That said, I don't think there's anything wrong with nesting <video>s, it's just unnecessary.) ~TJ
