Sony KDL-55HX701 Screen Resolution

To whom it make concern,

I just downloaded Mezzmo to be able to stream videos to my new TV. It installed well and played my stranded recordings fine. But when I wanted to add my DivX and other (transcoded) files, it always trancodes them into a small resolution that leaves black bars on the top and bottom of the screen. I of course want the system to transcode these files to fit my screen. Could you tell me how to do this. I have already messed with my KDL profile to try and use max resolution but that didn't help.

Sorry I can't give you all my log files but your system says they are all to big.

Thanks.
