Isn't it possible to have the internal processing of mediaportal think it's displaying in a widescreen resolution/windows, say 1024x576, so all video's and image are rendered that way. For example they keep their aspect ratio, so square pictures stay square, and widescreen videos, will think they can display at that resolution, so they takeup a bigger part of the screen (just like on a real widescreen TFT). But when outputing/sending information to the the window or fullscreen, having it resized to 720x576 (to stick with the previous numbers given). So everything will be squashed, not cropped or anything. The image on the display will be of course in the wrong aspectratio, but when displaying via standard tv-out, and displaying it on a widescreen tv in anamorphic mode, it will be stretched horizontally. So the picture will be in the correct aspectration again.
This would solve many problems. Just process everything, incl. menu's as it were a widescreen resolution, but then resize it without keeping the aspectratio, keeping the vertical resolution the same, but only squashing together the horizontal information from 1024x576 to 720x576 (or whatever resolution). This can be done also for a window, but then you'd of course see a misformed picture, but when connecting to a TV and setting it up for anamorphic widescreen, it would stretch the window / fullscreen view to right proportions. The desktop and such would be of course in the wrong ratio's and such, but if using TV-out and windowed / fullscreen mediaportal, mediaportal would be displaying in information in the correct ratio's.
Just like NVidia nStantMedia is doing in 16:9 Widescreen mode.
