Something I've noticed while trying to rip my Star Wars Blu-Rays is that all the different opening crawls are marked as angles. Now this really isn't a big deal, but I'd love to show the movies to my GF's family, which predominantly speak Spanish.
Even though most of the video file is the same, I still have to use essentially double the disk space to keep a Spanish version on hand. And even if I use, say, MKVToolNix to get both angles into one file, the file with both crawls is now somewhere in the 80GB range.
Is there a way to save the different angles to the same file with minimal space loss?
