Comment (by gtgj at pacbell.net):

 Okay, I just tried 1280x1024 resolution on a 1920x1080 display.  With the
 patch, the OSD fonts look correct and look the same as they did with
 1920x1080 resolution.  This is with 1080i, 720p, and 480x480 bttv videos.

 GetOSDBounds tells the OSD its width and height in "video" pixels.  I
 think that it is sufficient to tell the OSD its physical aspect ratio (not
 the display aspect ratio) so that it can scale its widths appropriately.
 Then, only the VideoOutput class needs to be aware of the actual display
 width/height/aspect -- as long as VideoOutput scales/frames the video so
 that the OSD ends up shown with the correct aspect ratio.  This is
 automatically true in normal operation because I think VideoOutput ensures
 that the video is displayed with the correct aspect ratio, and in normal
 operation, the video aspect ratio is the same as the OSD aspect ratio.

 This is what I was trying to accomplish by adding "aspect" to
 GetOSDBounds.  I think you're probably right that "XJ_aspect" is not the
 appropriate number in some letterbox modes but I guess I'm still a little
 unclear how the various modes are supposed to look like with different
 display aspect ratios.
