I recently updated my Sony E308 DS that came with Windows 98 to Windows XP Home Edition. There has been one nagging problem and neither Sony nor Microsoft are much help. The CD-Rom will work but the DVD does not. My husband and I do not exactly agree on what to do. He's insisting that a driver is the issue and I however think that a program (ie) Cineplayer for example is all we need to do. They advertise a decoder pack which will enable you to play DVD movies. Any help out there? I won't ask who's side you are on. Thanks
