Although they show in the list none of them work. Is this a particular problem with WMP 11. They were all ok in WMP 10.

I am on XP SP3.

not sure ,but check in tools/option and plugins and make sure thy are added

They all show in tools/plugins/options

They all show in tools/plugins/options

i google your problem and some of the post go back to 06 with people having same problem ,read a few and they suggested going back to wmp 10 try it to see if visualization works ,then keep it or reinstall wmp11 and try again

Thanks, that's what I found.
