Subject: Resolved problem with embedded videos!!
Update--I found a fix to problem of not being able to play embedded videos (such as on the flixxy site) from a limited user account with ie8 and Windows XP. Problem is apparently related to a recent update to flashplayer &/or shockwave, in combination with ie8. It seems that a similar problem can occur with Vista/Win7, though I don't know if it is actually the same problem with the same fix, or just the same symptom.
Here's what fixed the problem on my computer, perhaps it will help other flixxyites. See the following link:

"The latest build of Flash is 10.1.82.76, a security update. The installation of that update created a permissions conflict on my system and at least one other which caused embedded Flash content to not display.
The fix for this is to uninstall Flash and then delete the following registry key (Admin rights will be required).
HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/x-shockwave-flash
Then install Flash and the permission mask should now be correct. A quick test of embedded content will confirm."
After trying various ideas over the past three days, this was the only one that worked for me. For those unfamiliar, you can get to the registry key by doing Start/run/regedit. Then keep expanding each section til you get to this particular key. Right click on it and delete. You might want to set a restore point first, just in case things go wrong. Start/All Programs/Accessories/SystemTools/SystemRestore then choose create a restore point."
It worked for me, too!
