Blaze72: I've looked up ways to do it and it says find the game.gog file and rename it to game.bin and then use IZArc to extract the video files from it
which i do but then when i start the game up after doing all of that. The colours in the game are all wonky.
I'm not sure what's causing the wonky colours for you, but I can confirm that it is
definitely possible to get the cut scenes working. If I remember rightly I did those steps you described, then using IZArc, extracted the 'movie' folder itself into Blood's folder. So that's the whole folder then; just chucked it in there - didn't bother with extracting only the contents of the movie folder, or specific files.
If you've set it up anything like mine you should now see a folder called 'movie' in the game's folder.
BTW - which version of BloodGDX are you using? I'm using BuildGDX v1.02 (now integrated with the latest version of BloodGDX) if that makes any difference.
Good luck, and please let me know if you get it working.
