I use both at the same time. HT has my best collection of 3D iso's and UHD disks. ZDMC everything else including HT collection. Works well for me. There are pros and cons for both. HT can put all version of the same move (3D, UHD, HD and trailers) in one movie page. Kodi will list all versions as separate movies (pages). ZDMC scans movies and TV series better, can show full screen artwork etc. The lists can go on long on both sides. Main problem with ZDMC is lack of connection to the Zidoo player. Take it or leave it, not open source. We probably don't want it to be open source.
