That's a fair summary. I would just add that the plugin can also mount the ISOs, play from folder structures or play single m2ts/evo files. As you said, it won't have the menus, only the main movie. On discs that have more than one version (Theatrical and Unrated), it will always pick the one with the longest run time. On movies that have seamless branching (more than one file for the movie), the plugin can be annoying when switching files (Forgetting Sarah Marshall is a prime example). I'm still trying to find a way to fix this but this is where the MKVs or the PowerDVD option comes in handy.
