While trying to figure out how to make Skyfire 3.2 with built in Flash 10.2 to work on my PE (plays videos but I can't get little Buffer screen to disappear), I ran across a few websites that will work with the PE's Flash Lite. In order for these to work you CANNOT have any other Flash installed (like Flash Player 10.1). Please add to this post if you run across additional sites.

Comedy Central (just watched Dark Lord Minions, Wii Fit Girl (tosh.0), and The Daily Show Week in Review April 11, 2011). There are hundreds of clips available.

ESPN (just watched the Dunk of the Night)

Daily Motion

American Idol
