ATSC With Grey Border?

Whenever I play back ATSC files created by Windows Media Center on XBMC, I get a gray border on the bottom of the screen. The same files played back on MPC-HC or WMP don't have this visual anomaly. I'm curious if it's due to the embedded text stream. Is there any way to fix this?
