I tested it with one from Steam and it worked for me.
Was this with WINEDLLOVERRIDES=winegstreamer=d and a clean prefix? I don't think vanilla Wine with builtin amstream & quartz should work with this type of video when gstreamer is disabled. I could be wrong about that though.
Unless the Steam build has the videos encoded differently? Attached output of mediainfo for the opening video for the GOG build.
