If I include YouTube content on my site, they see a nice thumbnail from the video and a big play button. If they are on dial-up, they don't have to download it. Autodownload, to me, is flawed. I know I can set up the image and video stuff with JavaScript to work like YouTube. But if the user DOESN'T have JavaScript on, they are stuck with nothing. I would love to see an "autodownload" attribute to complement "autoplay" or use "autoplay=0" to disable the auto download. A way to add a thumbnail would be nice while not auto downloading.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BLOCKQUOTE type="cite"><FONT class="Apple-style-span" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;">The DOM attribute </SPAN></FONT><FONT class="Apple-style-span" color="#FD3D00" face="Courier" size="3"><SPAN class="Apple-style-span" style="font-size: 13px;"><B>currentRate</B></SPAN></FONT><FONT class="Apple-style-span" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;"> is the rate at which a media element is currently playing.</SPAN></FONT></BLOCKQUOTE></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I'm guessing this would be in frames per second?
