Itunes has my system all screwed up. My DVD drives keep going bye bye. So I found the regedit trick where you remove the upper and lowerfilter entries BUT, my system is not showing LOWERFILTER. I was getting my info straight of the microsoft page, and it said after you delet the upperfilter and then see no lowerfilter, click a link to see more info. Well, guess what, THAT LINK WILL NOT WORK. Im so mad now im about to smash every Iphone and Ipod in my house and write a NASTY letter to apple. Can someone PLEASE HELP!
