Since you've made this point in the past and you're on the -dev list,
I assume you're working on a solution to this problem.  When you post
the patch, please put "[PATCH]" in the subject so someone will
be sure to notice it and get it committed to CVS ASAP.

Since you're looking at this and working on a patch, I assume you already
know that the scaling is done in hardware after the OSD is drawn on the
video, so in order to get the OSD to NOT scale with the video when zoom
modes (either the 'W' key or manual zoom) are used, then you'll have to
dig into the OSD code and modify it so that the OSD is actually scaled
DOWN onto the original video so that when the video is zoomed in
hardware the OSD ends up being the proper size.  Also, make sure that
your patch handles the case where the user zooms out since manual zoom
allows this as well as making the OSD draw at the proper position on
the video since manual zoom also allows you to reposition the video
on the screen in addition to zooming.

Thanks for your help and we appreciate your time spent coding on this.
