Image crop in hdmi with pioneer dvr-550hk

I have a Panasonic th42pe7u plasma.
When I look an image (4:3)that come from the pvr in component, the image is near perfect.
But if I look the same image to the hdmi from the pvr, surprise, my image is crop 1 1/2 inch left and right, in full.
In 4:3 on the tv I have 1 1/2 inch black strip on left and right (space of the crop image), same for zoom.
Can you verify please?
