I know this is an AppleTV forum, but this seems to be the best forum to put this. I have a huge MKV video collection. I can't possibly convert them all to mp4. I watch these movies on my TV by plugging my laptop into it with a DVI to HDMI cable for picture, and line out audio minijack, to rca for audio.) Basically this just turns my 46" Samsung into a large computer monitor, and then I play the movie I want in either Quicktime or VLC. I control volume and playback using my laptops remote. Stone-age perhaps, that I have to plug it in every time, but it works for me, and again, I don't want to convert a thousand hours of MKV's, and even if I did they wouldn't even come close to fitting on the drive of one AppleTV let alone three of them. So, all I want to be able to do is catalog or organize these movies in my Finder, or through a Third Party App, so I can easily search them based on various criteria: genres (not just one); actors; directors; year, Academy Awards, IMDB User Rating; etc. MetaX wont add Metadata to MKV's, so that's out. Any suggestions?
