Why am I not able to capture videos playing in Windows Media Player?
Media Players and games display videos and animation using a special “accelerated” video mode. To capture such applications, you need to disable hardware acceleration. To disable hardware acceleration from within My Screen Recorder, on the Tools menu, select Settings. Check the option Disable hardware acceleration during recording from under the General tab and click OK. Note: this option is disabled under Windows Vista. Hardware Acceleration will be restored to its original setting once the recording is done.
