--- Comment #91 from Christopher Thielen cthielen@gmail.com --- I think this bug may still describe an error playing videos in more than just the game referenced. Here's Ultima IX trying to play its intro video using Wine 5.12. I believe I have the correct gstreamer plugins installed as the video files used by the game play in 'gst123' and GNOME Videos:

Does this look like the same MPEG splitter issue?
