I downloaded the ESB MKV file and bought a large enough USB stick to fit it. I then plugged it into the USB slot of my Bluray player and started it playing.

The video looks great, but there is no audio!

Any suggestions? The bluray player is connected via HDMI into my home theater amp.

The audio from the AVCHD I burned of Harmy's Star Wars (to a bluray disk) works fine.

The only way my Panasonic BD players will play both audio and video from an MKV is with 1 AVC track and 1 AAC track. You have to convert the audio. I recommend Xvid4psp, it works like a charm.
