If the movie was downloaded from a web site the movie may have been coded with Dvx . Search on this site for free dvx player and see if the movie plays . If so you can remove the free player but keep the DVX codecs and the movie will play in WMP . Microsoft doesnt supply DVX codecs for WMP . this will work in WMP 8,9,10 versions . Hope this does it
My neighbor is having a problem with media player where she can hear sound, but there's no video. The codecs for this are set to automatically download, so that part seems to be okay. I tried updating media player from 9 to 10, but that didn't work. Then I tried updating the video drivers(not sure if it would make a difference or not) but still the same thing. I ran something called System Suite 6 on the system to make sure there were no errors or windows file system problems. Is there anything else that can be done? This one has me stumped.
