I have recently started having problems when trying to open .wmv files when sent to me attached to e-mail. The relevant multimedia software opens either real or windows media, I then get sound but no visuals. The same happens if I save the file to the desktop, and try either of the programmes again.
I can however view the content if I use VLC, opening the content from the desktop.
I am not aware of changing any settings, and this problem has only recently manifested itself.
I am trunning Win 7, which is fully updated, with MS Outlook 2003.
I would appreciate any advice that might help me solve this issue.
