Hi Inquisit Team, I programmed a script on my one computer and my videos (mp4) run fine on this machine (as well as on another one in the lab). When I transfer it over to another computer though, the script runs without any errors - yay for this - as if the video is playing as it should, but it's just a blank white screen. I've installed the proper codecs and everything. I also programmed it in an updated version of 4.0 ... any ideas what might be going on? Thanks,Nick
