lol you've misread, i want the video to run while im gone, not as im leaving (because it will surprise them this way. don't worry about it though, the batch file part is written, I didn't even have to d/l the vid, wrote a batch file
start iexplore http://youtube.com/watch?v=eaE9hvLvfbs
then set it to run as a scheduled task and repeat itself every 1 minute or so
Thanks to LSB for helping me set this up in IRC
if you the scheduled task to run the file off your hard drive, pulling the internet wont fix it, and auto repeat
but that way does work :P
