I have a NVIDIA GeForce FX 5200 and my tv-out function is turned on (I don't know how, I think maybe because I have a video iPod that I connect to my PC? But I have viewed DVDs prior to tonight and after I got my iPod... so I'm not completely sure) and I don't know how to turn it back off. It is disabling me from viewing DVDs because Windows Media says that it is "Error 0xC00D1167: A problem occurred with copyright protection." Please help!! Thanks!!
