Disabling Hardware Acceleration (Windows 2000/XP)
Disabling hardware acceleration may be required to record videos from a media player such as Windows Media player, RealPlayer or QuickTime. Otherwise, a black screen is recorded. However, some applications like games may not work when hardware acceleration is disabled. Disabling hardware acceleration results in much smoother recordings since few system resources are used.
Turn off Hardware Acceleration while Recording
To disable hardware acceleration, click Tools >> Settings >> Display. Enable the option Disable Hardware acceleration during recording.
Note: Disabling the hardware acceleration using this method causes a black screen to appear for a second when the recording process is started and stopped.
Turn off Hardware Acceleration System wise
To turn off hardware acceleration in Windows 2000/XP, right click on the desktop, click Properties. Select Settings >> Advanced >> Troubleshooting. Move the Hardware Acceleration slider to None.
If the necessary options are not present for manual disabling, check with the manufacturer of your PC for a video driver upgrade.
Note: Disabling hardware acceleration system-wise slows down video performance for all applications, but it eliminates the black screen that appears when starting and stopping the recording.
Turn off Video Acceleration in Windows Media Player
You may need to turn off the video acceleration in Windows Media Player to avoid recording a black screen. In Windows Media Player, click Tools >> Options >> Performance. Move the Video Acceleration slider to None.
Download the Latest Windows Media Player
If none of the above solutions work, check the Windows Media Player version you have. You may need to download the latest Windows Media Player and that should solve the problem.
