Yep, using ems is the easiest way to achieve text and content resizing.
Looks good.

The captioning is interesting - it is too bad that you can't use the
FLVPlayback component - we've recently provided a set of skins for this
component that support captioning
(http://blogs.adobe.com/accessibility/2006/10/captionskins.html). In a
quick test it looks like the cc button you have doesn't work beyond the
current caption - when the next caption comes up the captions reappear
even if I turned them off with the button.
