This is the message that WMP11 post while am trying to play some DVD. Actually its my first time to encounter such error. I tried lowering the screen resolution and the color quality settings as suggested but still no luck. I have ffdshow installed as my codec and I have been using it eversince without a problem. I tried to play it on my dvd player and it works fine. I'm hoping someone here can give me a solution. Thanks in advance.

Sounds like WMP 11 doesn't like ffdshow or it isn't properly setup.
