In December I purchased Beyond Media with the Firefly remote from Snapstream for my new HTPC that I built. I love it and it keeps getting better with all of the free 3rd party software that is available.

Beyond Media is a software application that transforms ordinary PCs into all-in-one entertainment centers. Beyond Media sorts and plays music, photos, videos and DVDs. Its full-screen interface makes it easy to see and navigate from across the room.

Plugin's (xml & compiled code) extend the functions of Beyond Media. Some of my favorites are:

DVD Library

Watch your movies anytime, anywhere. Supports automatic importing of movies recorded in BTV, and supports importing previous ripped VOB/ISO/MPEG/MP4/RMVB files.

One of my favorite functions is when I use it with Daemon Tools to automatically mounts .ISO images. I use ZoomPlayer Pro for my player.

Movie Showtimes
