Why does RealPlayer have problems or crash when I try to play a video clip?

To give you the best video in the fastest possible way, RealPlayer uses the latest optimized video standards. Not all video cards or their drivers will function properly with this optimized approach. If a video card or its drivers is incompatible, you may see unexpected results.

Symptoms

RealPlayer crashes (shuts down or freezes unexpectedly) and "Invalid Page Faults" occur when you try to play a video.

Explanation

These problems occur when your computer is using a video card that does not understand the instructions that RealPlayer is giving to it.

Solutions

(These steps also can resolve distorted video.)

You may be able to resolve this problem by:

Solution 1: Set your video display to 16-bit color.

RealPlayer requires 16-bit (65,000-color) color depth. If the video card is not capable of this, you will receive an error message when you start RealPlayer that requests that you increase the video resolution.

To check your color settings (Windows XP and Vista):

  1. ON YOUR KEYBOARD: Hold down the Windows key and press R.
  2. Type desk.cpl
  3. Click OK.
  4. Click the Settings tab. (Windows XP only)
  5. Select Medium (16 bit), True Color (24 bit) or Highest (32 bit) in the color list.
  6. Click OK.
  7. Restart your computer if prompted.

Solution 2: Update your video card drivers.

Video cards use driver software to send information from the computer to the video card. Drivers that are out-of-date, damaged, or not DirectX-compatible can cause video problems. Update your video card drivers, and visit the video card manufacturer's web site to verify that you are using the latest DirectX-certified drivers.

Solution 3: Vista users: Copy MOV files to a standard hard disk.

If you use Windows Vista and have QuickTime 7.6 installed, you may be affected by a known issue with QuickTime playback from SATA hardrives connected to NVIDIA SATA controllers. IDE hard disks are not affected by this issue. If your computer has a standard IDE hard disk, you can copy your video files to that disk and play those copies of the files in RealPlayer.

Solution 4: Install the latest version of DirectX.

DirectX is another set of drivers that sends information from the computer to your video card. RealPlayer uses the DirectDraw features of DirectX to optimize the video presentation. DirectX is a component of the Windows Operating System. If the DirectX components are out-of-date or damaged, RealPlayer can crash or display the video incorrectly. Install the latest version of DirectX from http://www.microsoft.com/directx.

Solution 5: Disable optimized video

If you have tried the solutions above and are still having problems playing video, they may be caused by a video card that uses WinDraw drivers instead of DirectDraw drivers. Disabling optimized video in RealPlayer will improve compatibility for video cards that are not DirectDraw-compatible.

To disable optimized video in RealPlayer:

  1. Click and select Preferences.
  2. Under Category, click Hardware.
  3. In the Video Card Compatibility area, adjust the slider to the farthest left (Most reliable) position.
  4. Click OK.
  5. Restart your computer.
