5:4 aspect ratio

[gabortel]

It would be nice to have 5:4 aspect ratio for 1280x1024 lcd monitors in Settings > General > TV shape.
Adding the lines below to npvr's config.xml does not do the trick; the new option does not show up in the dropdown list.
<AspectRatioModes shape="5:4">
<AspectRatioMode name="Fill">0,0,1,1</AspectRatioMode>
...
</AspectRatioModes>
Probably a modification somewhere else is also needed.

Thanks a lot!
