Aspect ratio settings - (zoom, letterbox etc) for 16:10 monitors)

[Skweek]

Hi all.

some odds & sods that someone might find useful;

I've found that a fair amount of content on UK free-to-air channels is letterboxed 14:9 (oddly I've yet to see anything 16:9 letterbox, although I've heard it does happen), but there's no aspect setting for this format in GBPVR's default configuration file.

I've renamed "remove Letterbox" as "16:9 Letterbox" and added a "14:9 Letterbox". Below is the relevent bit of config.xml. The numbers are bit messy - I arrived at the them pretty much by trial and error, so they probably don't correspond with correct mathematically derived ones.

Note the global zoom of 1.07 to make better use of my 16:10 monitor (the left/right cropping on 16:9 and top/bottom on 4:3 this imposes would normally be over-scan anyway), without it you'd need different numbers for the aspect settings.

"Zoom 1" and "Zoom 2" are for anamorphic content. I occasionally find that the use of theatrical 2.35:1 - 2.4:1 transfers of movies is gratuitous. These zoom them to (roughly) 2.0:1 and 1.8:1 respectively.

<HorizontalZoom>1.07</HorizontalZoom>
<HorizontalOffset>0</HorizontalOffset>
<VerticalZoom>1.07</VerticalZoom>
<VerticalOffset>0</VerticalOffset>
