I had tried that out before, but I picked out some random ones. They played just fine if I tried them directly. That said, I don't know if that particular scene was one of them. Probably not. And I don't feel like checking them all, so I would need to recognise it by name. Does anyone have the name of that particular scene, the one you get after you go back to the flying ship, before searching for clues in the second town?

The link you gave, with the conversions, will probably work too, since they're all converted in another format/container. And if you have the right codec for that, it will work just fine. I want to stress, though, that I didn't have any trouble with the other cut-scenes, even on their native resolution, so I don't feel like I need a low-res conversion of all those vids. It's definitely a codec issue, not that my computer is too weak to play the scenes in their resolution (or it would have had trouble with the other cut-scenes too).

So, if possible, I would rather have the high-res videos working, in-game.

I guess I could make some high-res conversions of (only) the vids that give me trouble, and put them in the folder. Maybe I could link them here too, for people with similar problems. But the problem remains of knowing which one in-game is which one in the folder. It's been a few weeks so I can't remember quite; but is there an easy way of recognising that? (remember with me the screen always went 'tab' and crashed, so I can't visually compare it, because I never see the cut-in scene that borks.)
