Hey Sammy2 - I know you mentioned issues trying to playback mkv's and had some stuttering. I was just curious if you ended up doing some codec manipulation on your end for WMC (I'd assume so) when you went to play on the Echo? (i.e. install Shark007 codecs, etc)
I remember you saying that you use MPC-HC with Lav but nothing else for WMC so was interested in what you ended up doing to play mkvs to the Echo.
