OldFatGuy: I just played Two Worlds a few weeks ago on my Win 10 laptop and it played the opening and cut scenes just fine. Am I misunderstanding the issue here?
timppu: What version of Windows 10, have you run all the latest (feature) updates for your Windows 10?
It seems this problem came with certain (feature?) update in Windows 10. Maybe Win10 dropped support for that codec that those videos need, or something.
If by version you mean whether it's Pro or Home version, as I said above I'm not sure. And if you're talking about a specific numbered version, again, as I said above it's a bit too much of a PITA to go get it and fire it up and look.
As far as updates and such, yes, that laptop was completely up to date with any new "features" that Microsoft added. I do want to add though, as I've started several threads on the topic.... Microsoft updates VERY OFTEN break games for me. Games that would run fine one day would not run at all after an update. This has happened so frequently that now whenever I get an update, the very FIRST thing I do is start firing up all the games I have installed to see which ones (if any) are now broke. And the number of times something is broke far, far, and I mean far and away leads the number of times nothing was broke. But by discovering which game(s) it is, I can then get a headstart on finding any fixes for it.
One example would be Eschalon Book 1 (and 2.. not sure about 3). A Microsoft update borrked the hell out of them... but within a day I found a "fix" that returned my ability to play it again (IIRC it had something to do with "legacy gaming" or something that the update had unchecked and it needed to be checked).
I don't remember specifically Two Worlds being one of the games affected recently.... although I do remember it being one of the games an update broke... but that was like at least a year or more ago. And I don't remember the "fix" either. I just remember an update when I went through my ritual firing up all of my games that Two Worlds was one of them on an update some long time ago (it may have even been two years ago I dunno).
I feel very badly for those that have this issue because, as I sad, the cut scenes are an integral part of moving the story forward... and it's a good story (IMO). It's truly a great game IMO. I love it and have played it multiple times and have been thinking of playing it again now. Funny thing is though, despite loving the game and having played it multiple times.... I've still never even installed Two Worlds 2 despite owning it for several years. lol I'm not sure what's up with that.
