Separate 2 bluray movies from single disc

Hi everyone,

I have a question for the forum...

I own the Bluray disc Grumpy and Grumpier Old Men and would like to split them into two movies so I can more easily access them in my XBMC library. I took a look at the disc structure in Windows, but didn't see anything obvious that might lead into finding a way to split the disc movies.

Has anyone tried this before, and if so, how did you split the movie?

Thanks,

CN
