I have no idea what might be causing this problem but recently when I try and view some of my widescreen movies, they will only play in full screen. Some movies ask at the menu to choose either FS or WS. I select WS and it shows it as FS. Many of these movies I've had for awhile now and this just started happening. Any ideas on what might cause this sort of problem? I have a JVC XV-M567 3 disc changer DVD player.
