Here's an odd behavior in the mediaplayback component. I swear this wasn't the case pre Flash 8. When I load a FLV file into a mediaplayback component with contentPath, it plays back right away. However with an MP3 the component buffers/caches the entire clip before playing it back. You'd think it would be the other way around, right? AutoPlay is set to true in both cases.
I've messed about with the publish settings audio event & audio streaming, but it makes no difference.
