The videos all have graphical glitches with black pixilation. When in game, the cursor leaves a trail and blurs the graphics so the game becomes unplayable. Playing the game in DxWnd under its default settings works but the movies are missing.

same issues as you're facing.. really annyoing

Actually, I tried on my desktop PC and it worked flawlessly

So, the issue might be hardware or driver related.

my laptop i had issues on was a Lenovo Yoga C940, That has Intel Iris graphics, with the latest drivers.. I wonder if it's a setting.
