I am currently messing around with an experimental HTPC set-up and am trying to get the best quality from the rips I have. Generally if I'm watching a film in a cinema set-up I use MyMovies and WMC but to do this I have been using Shark007 codecs to get the videos to play. However as I am on Windows 8 only version 1.8 of Shark007 is supported. If I play the a film in WMC and then play it again in VLC player, VLC seems to give better video quality. Does anyone know what codec VLC uses for .mkv and .m4v video files, or any good quality codec packs that support surround sound and work with Windows 8?
