This is my first time setting this up - I am able to stream a ripped blu-ray (mkv) to my 70 sharp aquos tv, BUT while playing on the tv, when I try to pause, stop, ff, or rew, I get a message on the tv that says: "invalid operation for this content"

I also tried download avi files as well with the same result.

any ideas? Is there a setting in mezzmo I need to set or something? the inability to pause, stop, ff, etc really makes mezzmo unusable for streaming ripped dvd's.
