Ps3 Display Black Bar Cropped Image On PS3 Playback Of Avchd?

Cropped image on PS3 playback of avchd? - ps3 display black bar

Hello.

I burned to a blank disc (with ImgBurn) 720p AVCHD files play on your PS3. Unfortunately, the picture is cut off or very high, around a large black bar at the bottom of the screen. (Based on nearly 1 / 2 pages), I can be part of the picture in the first place, but it is truncated on the screen but off screen as the picture is not the black bar is present. But if you play this file on my computer sounds good. I have also tried another file, verbatim:
Subsequently, however, was 1080p file, but had no problems. If this question? Or is it the way it was burned. I also tried the 720p files on my computer and is very good. Could a setting in the PS3?

Any help would be very grateful.
Thank you.
