I am new but it have worked at this a for a few days and it seem Mezzmo 2.4.5.0 has major limits in the the library tree.
If any one can help me over come this limits please let me know.

OK this is the issue. I have Music, Movies, New movies, Video clips from the web, Porno movies, Audiobooks, and Audio stories (text to voice). I was trying to add a few of these different types to the library and of course i don't want every device in the house to access all items. I need to keep the kids from the adult items. Besides Mezzmo locks up every time i add a large number of files at once, i always have to kill the program and most of the time all the files are listed when i restart it.

The problem, it seems that only three main playlists show up and if i add more playlist at the root it all looks OK but they don't work the same as the three main ones, and all items in my new playlists are add to the smart and active playlists in the three main library types of Music, Photo, Video.
The playlists i add show up on my Samsung TV in the root listing of all the three mail library types but don't list any files. Any playlist i add to my new audiobook playlist in the library root show up but also don't list any files. I have to go into the Music library and the playlist in there list the audiobooks and all other music type files.
I can delete all the pre built Music playlists and try and create new ones but you just don't have the option to separate the items. I think i can add my files to playlist folders under the main three playlist and then apply permissions and maybe they will not show up on some device not in the permissions list but it seems not to be working that way for me.

Is there any good way to do this. Can i have more the three main library types. Because if i make a active playlist of Genre i can not focus it on one type i get the genres of Music, Audiobooks, and My audio stories all listed together.

I setup a MediaMonkey servers in five minutes and it was very easy to do this. I have been trying this for days on Mezzmo and can not come up with a good way to do it.
