I am having a problem with PowerDVD 3.0. I can't get it to play any DVDs. When I try to play a DVD, the screen just goes black, then keeps clicking repeatedly, as if it trying to change the monitor resolution settings over and over. I can play DVDs just fine with other software such as ATI Multimedia Center 7.6 and Windows Media Player. PowerDVD used to work for me. I'm not sure when PowerDVD stopped working, as I only use PowerDVD when I want to do screen captures from DVDs. Can anyone help me get PowerDVD working? (I haven't been able to find any info on this problem when I searched.) Thanks.
