No prob, and maybe if some others will follow this thread they might get an idea of how much work might be involved ;)

Still a shame that I can't find what I have in mind....maybe I will come across it again. SO don't be surprised ;)

Do you have winmm.dll in your installation folder?

try renaming /removing it and let me know if it helped (you could also try finding it in your system folder, but only rename it there ;) )

That is exactly what I ended up doing with Wheel of Time. Since the best I could do was that the game could show the cutscenes as slideshows, I exited the game when a cutscene would play (e.g. between levels) and watched the specific .mov cutscene with the player (iTunes? Or I don't remember if I used VLC anyway.) which played them fine. Then I just continued the game.

I am pretty sure this is something what GOG has had to figure out with many of their games, not sure how they've fixed the issues. Not sure if it uses .mov, but I recall the cutscenes in my retail Return to Krondor don't work (they are just skipped IIRC), while they work on the GOG version.

Then I recall the fan based fixes for e.g. Blood Omen: Legacy of Kain where I think they even ended up re-encoding the cutscenes, maybe even offering the ability to download the higher quality Playstation versions of them for the PC version. Not sure if GOG has used re-encoded cutscenes with some of their games.

If you mean that mov files play fine in various Windows media players, yeah same here. But it is when an old game tries to play them where the issues start (I think usually the game just skips those cutscenes; at first I didn't even realize Wheel of Time had cutscenes, but I kept wondering what the heck the game was blabbing about when in a beginning of each level if would refer to something (story) that happened in a cutscene that should have just played just before the level).

Outside the game though, the WoT .mov files played just fine.

No

and there it was this dll

So as usual some windows stuff running in the background and screwing around ;)

I have seen quite a bit of those problems around. And if applying normal logic there it doesn't make sense at all.

I've got L&O: DotM, and I vaguely remember it using QuickTime Player to play the videos and handle navigation. I'll give it a crack later, but I have a feeling that you'll need to replace whatever QuickTime version the game has installed with it with ffdshow or Quicktime Alternative.

It could also be that those .mov files do not even have anything to do with Quicktime, as unless that whole software was included in the game's install CD, Apple would have had to allow the publisher to silently install and register just the qt-codecs with Windows.

More probable is that the cutscenes use some old version of Video for Windows, which is not included with later versions of the OS. Or in the worst case scenario, the game's internal videoplayer could rely on some outdated features that the GPU's driver or Windows itself doesn't support anymore.

I have had to fix the VfW problem for a few games in the past, but infuriatingly I have totally forgotten the specifics of when, where, what and how.

Removing winmm.dll from the game folder makes .mov cutscenes work (in Wheel of Time, Law & Order etc.)? Or what do you mean?

It's not in the installation folder, and even though I'm admin, it won't let me change the name of the file in the system folder.

Thank you for looking into it with your own copy! :D I have tried the QuickTime Alternative, didn't seem to make a difference.

To lazy to follow a link?
sugar.....And no, NO other program is needed to play ingame, they always came with ingame players, but windows is screwing in the background/

And not let you change it, might be because of Win10 or similar (restricted to system). But doesn't sound to be it (the file).

okaaay, back to he drawing board.....

Is it just me or most British avatar you have got there?
Anyway when I googled this game first page includes No Man's Sky.

(sigh) Yes, I followed your link. It talked about fixing a problem with Call to Power 2 not running at all in Windows 10. According to your link, it was fixed by removing winmm.dll from the game directory.

So I ask you again: is that the fix for making .mov cutscenes work in games that we are discussing in this thread? Was that a similar issue with CTP2 (ie. it uses mov files, and the game doesn't launch at all because it can't play them?) In my case with Wheel of Time, the symptoms were not similar at all, the game launched and played otherwise fine, but all the (mov) cutscenes would be simply skipped by the game.

just a bit further down:

And after also changing ccompatability to WinXP SP2 the intro video also now works

(sigh).....;)
EDIT: Sorry, if it sounded harsh, but it looked for me bit like you didn't followed the link, the link I provided first was just for showing WHY I suggested this dll NOT what it all fixed ;)
EDIT 2: and also somewhere else it was mentioned that the wonder videos had problems as well....all of them IIRC .mov files, which were quite often used during a certain period of gaming....

She's a spy sent here from the British, she's just not very good at it.

do me a favour
open cmd
go into your installation folder

and do a

dir *.* /S > filesxyz.txt

this will save the filenames into this file. with renaming (maybe even without) you shall be able to attach it here on GOG.

Okay, I think I did it right. https://www.dropbox.com/s/qw3enewjgh6kog9/filesxyz.txt?dl=0
