If you are "computer savy", then the upgrade should not be a big deal. Or, if you have your BDP-1 connected to the internet. If you are neither, and have a software version prior to "Looney Loone 1.75", then you are in for some challenges.
If I were you, I would contact Bryston and have them send you a pre-loaded flashcard with MM loaded, ready to go. Just be sure you get the latest release. They sent me a premature release and I had to manually add files to complete the update. With a preloaded software, you can always go back to your looney loones version if you don't like MM, so save your original flashcard.
But once you listen to MPD .187 you will not go back.
And Chris chuckles at those fuse mods...
