 	Hrm... I wasn't aware that was the purpose of 704x480.  I have yet 
to ever see that implemented that way.  The players I've tried it on you 
could see the video start playing cut, and then after about 0.1sec, 
stretch to full screen.  I thought it had something to do with being 
exactly 2x 352x480, or divisible by 16 or something.  </ignorance>
