Zoe and all, I concur. Spent the last week trying work-arounds. Long story short, nothing to do with conflicting plugins metadata htaccess etc. So the grand design to make media easier succeed in making our previous short codes obsolete while not providing a reliable alternative. For me it is down to audio not working reliably in Chrome. Who thought not to test Chrome? And now we have two more WP releases before years end to contend with. On the bright side 3.6 should give html5 media plugin developers a lot of new business.
