I add video files to the video editor, Both audio and video channels appear but only the audio plays. The video is just a white box. Anyone know what is wrong. Added video in WMV. Also tried MP4 same thing.
I already had a graphics cards driver problem with Blender. The developers helped me out to find out whether the problem is one with the driver.
You should use the opengl32.dll from http://download.blender.org/ftp/sergey/softwaregl/ and place it next to
blender.exe as described by sergey to find out if the problem is your driver. Beware, that Blender might be very slow while using this wrapper dll as everything is done on CPU only without using your graphics card.
