Welcome to the forum feksteen.
The reason the webpage has not been updated is simply that I started writing the program mostly from scratch, and the current 3.xxx builds are a work in progress, uploaded here for testing purposes more than anything else. Once it catches up to version 2.xxx in features then i'll update the webpage
As you noticed many of the menus have not been populated, although all movie functions are available via the tabs and context menu, TV shows is also not enabled yet, although TV shows are coming in the next week or so, as long as TVDB stays online, its been offline for much of this evening.
All in all MC gen2 (3.xxx) is a big improvement over gen1, but it still needs some work to have all the functionality of gen1
DVD folders are now automatically dealt with, no need to select it anywhere.
The preferences are also dealt with live, just change the settings you want, when you exit the screen they will be saved, although once again, some (non essential) preferences are not yet enabled, and some are now defunct, once tvshows is fully working then this will be my next target.
Feel free to play around with with the newer versions, and report bugs and ideas to this forum, but keep in mind that what it does, it does better than gen1, but it is by no means complete.
