I have a three-year old WDTV Live which I use for streaming local content (from a Synology NAS) to my TV. In almost all cases this is MKVs. For the past two years the connection has been over home plugs as wi-fi in our house is patchy. To be honest, performance has never been reliable. Generally I get to watch the film I want, when I want, but the unit seems increasingly sluggish to load (sometimes a few minutes pass before a film begins playing), I've had the unit freeze on me, and lately it has refused to play a 5.1 digital soundtrack in anything other than pro-logic mode. I know there are things I can try, such as a hard reset (no improvement), and I can check the throughput of the plugs (seems fine), etc. but frankly I've had enough of the thing and would very much like to find an alternative. I don't need lots of additional services or apps (we have a smart TV) and there's no need for internal hard drive support. All I want is solid, reliable playback of my video files over a home network. I like what I read about the new Rokus, but I'm open to any suggestions.
