In Emby, multi‑disc movies are stored as separate files named like xx‑cd1.MKV, xx‑cd2.MKV, and so on. Emby treats all of those files in the same folder as one single movie. Unfortunately, SkyBox 2.0 will only play the first file (xx‑cd1.MKV): it won’t automatically continue with the later discs, nor does it offer any manual way to switch to them.
