My O.s. is Xp. I have installed at my computer 2 video players: 1.Windows Media Player (WMP, version 11.0) 2. Another player, named IVIVO. Whenever I look at the content of my DVD drive, I can see that the video folder contains one or more VOP files. The icon that stand aside to the VOP file is an IVIVO and not WMP icon!! I can play my disks only by IVIO player, although I would like to play it by WMP. When I point to a VOP file on my DVD disk, then select WMP to play this file - I get an error message, and can't play it. (selectin IVIVO will play it!). I get the Same error message from WMP when I insert the DVD disk into my DVD drive, and after being offered to select what do I want to do (like: View files, Do nothing, Play by WMP, Play by IVIVO)- The same error message appears if I select to play it by WMP, but it is played if I select playing by IVIVO. I prefer to play it by WMP. My question: How can I make WMP to play my DVD disks.
This is a correction to the former thread that I myself have posted. The files that I can't play by WMP are VOBfiles, and not VOP as mistakenly I wrote in my first post.
