Why the recorded video is blank when playback?
This is caused because the player that is being recorded is using hardware acceleration. The solution is to disable hardware acceleration in the player before recording it. Another option is to disable hardware acceleration system wide. Because this effects all applications on the system, it may cause performance problems for some applications and others may not run at all. To disable graphics hardware acceleration globally for all applications on Windows 2000, select Control Panel> Display> Properties> Settings> Advanced> Troubleshooting, on other versions of Windows select Control Panel> System> Performance tab> Graphics> Advanced settings. In both cases slide the Hardware Acceleration slider to None.
