Check om realplayer og mediaplayer er installeret?

hmm.. Media Player er "altid" installeret på en Windows maskine.. :)
Den kan sikkert fjernes, men det er nok de færreste der gør det.. de vil jo sikker godt kunne afspille multimedia filer..

Jeg har desværre ikke noget svar på dit spørgsmål.

Check af Real Player plugin: http://view.dau.mil/dauvideo/browser_setup.jhtml
