I started with Windows Media Center then moved to Meedio then on to JRiver. For sure JRiver for audio but I like the tagging an organization with movies as well. Theatre View has a nice "by decade" and "by genre" and other sorts that are handy but . I mostly sort and select on my laptop or tablet and send the movie to my Oppo as a video renderer.
I have loaded & configured MB3 Server but don't have a client so I can't watch w/MB3 except with little expandable PC windows (I use windows 8.1 which doesn't have Windows Media Center...don't
the Windows clients require Windows Media Center?).
