I was actually surprised to find my settop box supported mkv, multiple audio tracks and can even display styled subtitles unstyled (it would need specific support for substation alpha to do this). Software support for 10bit was pretty much there in some form when they majority started using 10bit, it is a lot more wide spread now (mostly a few programs like mplayer2, vlc and MPC:HC). Support for embedded products (like settop boxes) will be a long time, or maybe never.
