I appreciate the response from both you and Renoir.  I'm reasonably familiar with the general principles for optimizing page speed and the yahoo page, http://developer.yahoo.com/performance/rules.html. Seems to me there is/was a video put out a couple years ago (Souders?) where the Yahoo tech guy did a nice job of laying it out in layman's terms, no, a great job.

Maybe I should have mentioned something else however.  I've become a specialist with the cms, Joomla and am using a component called HD Flv Player, www.hdflvplayer.net, to manager the videos and its plugins and module for display.  It's available standalone, also for Drupal, Wordpress, Zen-Cart, Magento, etc.

Without either recoding Joomla core or the component you are somewhat limited in what you can do. I'm trying to get out of hacking if it can be avoided.  Maybe what I should do is to run some performance comparison tests before I talk to what "feels" slow.

In the control panel, other than linking videos to those you have uploaded to your website or to a youtube-similar service there is an option to select Streamer Type of:


If you select rtmp you have to enter a Streamer Path (?). I have left it set to the default, none.  Does this help?  My bad for not being clearer up front.

I usually give iframes a centred loading gif background to give the end user a bit of feedback.

I've noticed that the player 'seems' to take longer as more videos are added.  Is this what it is or are there techniques to setting up playlists that are more efficient for downloads and such?
