Many thanks for fast reply, have tried just about everything i can think of but not having much luck. Don't think it is hardware related as am running on ibm thinkcentre p4 ht 3ghz 2g ram ati x700. xp sp2 Have worked around it for now by making a batch file run at start-up which sets colour to 32bit then starts vlc media player fullscreen and plays the intro video, when its done it changes the colour back to 16bit and starts GameEx. so start vid good, menu transitions good, just some screen saver videos not so good. (can live without them for smooth menu movement) I think the problem may have to do with the video codec i am using. I have had problems with fddshow codec crashing gameex in the past, and am using xvid 1.1.3 ..can't remember exaxctly why it was that i set it up this way now, was either something to do with daphne emu running rotated or video snaps not showing without it. am going to chicken out updating as have everything else just spot-on. (will try again when have another machine to try fresh install from ground - up ) was also wondering, is there a way to alter the aspect ratio of the media player that is used to display the videos when the screen saver is run ? ..I have the moniter mounted vertically in my cab and all the videos end up stretched "taller" than they ought to be. Many thanks, -Rich.
