I don't think so.

'VideoAspect * OsdHeight' is the width of a full screen subtitle display,
using the entire OSD height, according to the aspect ratio of the video
material. Dividing this by displayWidth (i.e. the actual width of the
subtitle display) results in the osdFactorX, which is used to convert
coordinates in the subtitle display to the OSD coordinate system.

Can you provide me with some sample recording that demonstrates the
problem you are seeing?
