Well first off Yuffster is a girl :) Second, I am not sure of the status of that plugin, I watch for new stuff there now and again. It is using the swiff mootools plugin so you should be able to easy access any of a flash-based player's exposed controls with it...
Not exactly sure what your question is though, I couldn't replicate the sound freeze issue you stated having in FF2,3, IE6,7, or Safari3/ Chrome. - Daniel
