I just set up a program to convert all of my online videos to FLASH format (the same format you watch if you visit sites like YouTube). So intead of just having Windows Media Videos available, you'll be able to select the Flash Player option as well.
I've already converted Excel 101 and 220 to test it. It seems to be working great. Unfortunately, it takes about an HOUR to convert one class, so I wrote a batch file to process them all. I have over 100 classes, so I'll be adding them to the web site as they finish.
If you'd like to test Excel 101 out, just log on to your account or go to the Theater and click on the FLASH PLAYER option (bottom, left side). Click on the Movie title and it should load up. Let me know what you think.
