Today I added a method which enables the Ambilight effect (both for Momolight and Philips AmbX system) with video playback (DVD, avi, divx, etc) using Windows Media Player Classic (WMP Classic). Listed below is the method for the Philips AmbX system. For Momolight the method is similar but requires less steps.

Windows Media Player (WMP) Classic: Start WMP Classic, go to view and select options. In the options menu go to playback and select output. In the output screen select under DirectShow Video VMR9 (renderless)**! Now restart WMP Classic and open a video (either DVD, avi, divx or something else). The Philips AmbX Application Manager will give a popup in the right corner of your screen saying a new application has been identified. Go to the Application Manager and enable WMP Classic! Again restart WMP Classic and open a video file, the Philips AmbX lights should now light up with every played video!
