I'm looking for "client" units that can stream from a server I have set up, playing mainly MKV and RMVB files up to 1080p, with at least 5.1 DTS output. A year ago I gave the WDTV Live a try but I found it extremely difficult to navigate to network shares, and there were also minor problems getting Chinese Unicode to show up in titles. I'm personally used to HTPC software interfaces, such as XBMC, GBPVR, etc.
What's the best solution? Is the Apple TV a good alternative? I don't mind paying $200 if it means it gets the job done, as it's still cheaper than buying a computer for the purpose. Should I wait for the Dlink Boxee?
