Elmofongo: I was playing all these games like a week ago, I haven't tinkered with them at all, but for some reason, the cinematics are not working.
Briefings before missions for the Thief games, the ending to System Shock 2. All of them suddenly are not working. Again, they were working fine not too long ago.
I had the issue with Indeo / Vimeo codecs in some old game once on a new computer. It was resolved by applying latest K-Lite codecs pack (a good addition to Media Player Classic). Try it, install the codecs pack (normal pack should do), restart your PC and let us know.
221bBS: Try using
Voodoo 2 with it. Just dump everything in the "MS\x86" folder into the install folder. You also might want to configure it to get rid of the watermark and set resolution.
I've installed Voodoo 2 with Thief recently and it seems to work well. I haven't really started playing the game yet, just played a few minuted to make sure everything was OK.
Voodoo 2 worked well with a lot of older windows games.
And how exactly an alternative wrapper for the game engine might help with cutscenes not playing?
