Aspect ratio placement problem

My problem is that I switch between two screens (16:10, and 16:9), and these two elements below (a star rating right at the middle of the screen), although perfectly aligned on my 16:10 screen, are way off on the 16:9 TV. First is an image of empty stars, and the second is the actual rating if present.

                    <control type="image">

                        <top>75</top>

                        <align>center</align>

                        <height>25</height>

                        <aspectratio>keep</aspectratio>

                        <texture background="true">rating/none.png</texture>

                    </control>



                    <control type="image">

                        <top>75</top>

                        <left>881</left>

                        <height>25</height>

                        <aspectratio align="left">keep</aspectratio>

                        <texture background="true">$INFO[ListItem.UserRating,rating/,.png]</texture>

                    </control>
