Removed a redundant "render" call from the zone's "play" function. There was a race condition between the layout and the zone both calling "render". In addition, the layout render function was explicitly setting it's container's "left" property to -2000px, but it *also* called "hide" on itself, which set the left property to -2000px again. I removed the redundant "hide" call.

Otherwise, I cleaned up the code that switched behavior based on whether or not "pre-buffering" was turned on. We never did get any pre-buffering to work.

Finally, I added the nocache="1" directive to the embed tag. This seems to improve playback (thus far).
