Try the link I posted in the first page of this thread. That codec pak may do the trick (depends on the video file type though)I actually have the same problem as him. I updated from 5.08 pro to 5.12, yeah .08 worked perfect, but in .12 - no video. Sound works fine but video does not play (and yes the stupid video window was open it opens automatically if you know how to use the options menu.) Someone should definatly give me the codecs cause I couldn't find them last night.
