AVCHD Disks not playing OAR on Panasonic BD60?

[Itaintrite]

It seems the player auto-crops the video to fill up the entire screen. Is there a setting on the player I can change to force it to play the videos at OAR? Or is there a different way to convert the MKV videos to AVCHD that will force OAR?

I'm currently using TsMuxer 1.9.9 (add blank playlist unchecked).

Thank you.
