I don't use it too often, so I'm not sure when it started, but when I try to play any YouTube videos it will load up and start playing the sound only, with the QuickTime logo. At first I thought I could do without, but the longer I go, the more I realize how much I used it. I was wondering if anyone else had this problem and knew of any way to fix it.
I have safari download manager, mxtube, Oplayer, and ifile installed, along with carols other jb apps, but those are the only ones I think could possibly cause an error.
