I have been using (and proselytizing) JR Media Center for over twelve years now, I am a big fan. No other collection can handle 200,000 MP3s, hundreds of movies and over 50,000 photos. I also now use Subsonic because it provides easier external access to my audio for my family and me (via iSub for iDevices & a great web interface for everything else). I would love for MC version 18 to be able to push MKV (and other) video formats to iDevices (locally and over the Internet) so I don't have to find yet a third product for this functionality... iSub is limited by Apple's strangulatory (just made that word up for this) restrictions so MC could fill a huge void. Please...?
Thanks,
