Windows Media Player Troubleshooting
If you are experiencing problems playing a Guild Wars video using Windows Media Player, the issue could be related to your settings. One common symptom is the audio track playing, but the user not seeing video. Here's a potential workaround: go into Tools > Options.
Can't find the Tools menu? The Menu Bar might be hidden from view if the Windows Media Player window isn't in full-screen mode. To access the Menu Bar, either maximize Windows Media Player or left-click the downward-facing arrow to the left of the minimize button in the top-right corner, then select Show Menu Bar from the drop-down list.
Click the Performance tab and select Advanced in the Video Acceleration Settings area.
Uncheck the Use Overlays box under Video Acceleration, then click OK.
