Yup, perfectly right.

Probably will need to re-init the OSD class with the new numbers.  In 
NuppelVideoPlayer.cpp, the ToggleLetterbox function, you should probably need 
to do something very similar to NuppelVideoPlayer::ReinitVideo(), but without 
the call to videoOutput->InputChanged() and ClearAfterSeek().

I'll get this patch applied shortly, thanks =)
