Panny Viera - Won't play x264 HD

Hi,
New to all this but on my Panasonic Viera L32D25B i'm having some issues playing any MKV x264 content - I thought using the Viera profile serviio would automatically transcode, but i suppose various Vieras probably have different file formats - so perhaps i should create my own. Though i'm not sure what file types my device supports!
Where's a good place to start? Sorry if i've missed something in one of the Help / FAQ posts.

Renderer : Pansonic Viera L32D25B
Server : Linux Debian Sqeeze, Serviio is latest as of Writing (0.6.0.1), FFMpeg version is SVN-r0.5.5-4:0.5.5-1.
Server has loads of free RAM, and loads of free storage space.

Anyway i'll paste what i've got, so far..

FFMpeg Output

  Code:

Input #0, matroska, from '300.mkv':

    Stream #0.1(eng): Audio: dca, 48000 Hz, 5.1, s16
