I have had my harmy despecialized editions quite while right know in AVCHD format burned in to discs and just recently i bumped into a video of another persons disc versions with an star up menu with whole bunch of extra stuff like documentaries and a very cool video backgrounds. So i came to wonder is the start up menu some kind of a extra downloadable feature or did i download/burned my films incorrectly?
The DeEds are just the films, other people do menu authoring and various extras. Although the AVCHD versions you have are lower-bitrate than the MKVs, so these Blu-rays would also look (slightly) better, and they’re probably more current versions too, which would make them noticeably better.
