saya pake media player versi baru,real player versi baru.
tapi setiap kali mau play dvd.
selalu muncul :

Windows Media Player cannot play DVD video. You might need to adjust your Windows display settings. Open display settings in Control Panel, and then try lowering your screen resolution and color quality settings.

kira kira permasalahannya dimana yah? resolusi dan quality setting sama seperti biasa kok.
masalah ini terjadi setelah saya instal windows baru.
