I read that there was low res and high res movies. I wonder if some videos only have the low res versions on the disc. at least from what i see of the first 3 discs things look pretty similar to the steam version. The cam data might not be needed as we currently aren't using it.
I might put that list into the code to make it easier to tell which movie is what.
Now for some stabs in the dark since I'm unsure why it's not working I'm gonna list some ideas.
One thing I was wondering is if you had all the required libraries installed. I assumed you did or else it wouldn't let you build I think. If you goto Tools > NuGet Package Manager > Manage NuGet Packages for solution. You should have:
FFmpeg.AutoGen v4.1.0.4
MonoGame.Framework.DesktopGL v3.7.1.189
MonoGame.Framework.DesktopGL.Core v3.7.0.7
MonoGame.Framework.OpenGL v3.7.1.189
NAudio v1.8.5
NAudio.Vorbis v1.0.0
NVorbis v0.8.6
Maybe you could put a breakpoint in Game1.cs maybe at the start of Initialize(). Just see to if the code fails right at the start or if it stops at a certain point. I'd step over stuff at first to see how far you get than step into a function it crashes on. Assuming it lets ya.
https://stackoverflow.com/questions/4052770/deciphering-the-net-clr20r3-exception-parameters-p1-p10 has some info how to read those CLR20r3 messages. I am unsure if I can run the command on my FF8.exe or if i'd need your build to see the issue.
Might be worth trying to Build -> Clean Solution.
lol it's late i should get going.
Maybe Maki will have some ideas when they get back.
