Agreed, what is it that you liked about Kaleidascape? The disc storage vault?
I was highly tempted to install my movies, purchase anydvdhd, and start backing up all my discs to my WHS without any intervention on my part.
I didn't because there seemed to be no way for any server client to transcode Video_TS or iso. I went the MakeMKV route, and now I'm over 150 discs in. I've only got 20 left, so I'll stick with this route. I don't miss the menus a lot, and when I want to watch the extras I'll probably go grab the physical disc and play it.
I've been keeping plans for an upcoming tablet on the horizon, so I didn't want to put in a lot of work and alienate the possibility of watching any of my content on a tablet later.
Mediabrowser, Plex, XBMC all look good to me. I never can make up my mind
