SV8 is not a container format. It's a new version of the entire format which adds features like container independence, proper streaming and cutting, chapters, and takes care of extendibility. The codec is 1.16 but with internal clipping eliminated. Seeking is instant regardless of file length. File size is 2% smaller due to improved bitsream compression.

SV8 ".mpc" files are now Musepack streams within an mpc container. The simple mpc container format is designed specifically for Musepack audio streams. It's not mandatory to use it. Encoding to raw streams to be embedded in other containers is possible. The mpc container is directly controlled by us and thus guaranteed to have fully working support of the format at all times. Third-party containers supporting the format will most likely work just fine, but since we have no control of them we can't guarantee support to be in order at all times. That's a main reason for maintaining a container of our own.

So there's not much to distinguish , mpc files are still always Musepack audio files. An mkv file with a Musepack audio stream would be a Matroska video file with Musepack audio, not codec (there's no coder or decoder there, just a Musepack audio stream). I understand the confusion though, "codec" is a widely abused term.
