Do any of the gtv devices stream the following: 1. MKV 1080p/5.1 natively (no transcoding). If yes, what app or media servers work with gtv? Can it do HD audio? 2. Stream 1080p/5.1 netflix 3. Stream 1080p/5.1 amazon 4. Stream 1080p/5.1 hbogo I currently have a roku in my bedroom and xbox, ps3, atv2 in my living room. The big limitation is mkv files for me. Currently plex/ps3 media server can remux but it is a huge head-ache at times!
