Yes, sounds good. I read the value would be pixels for vdr 1.3.x ?

At least in current vdr the OSD-height is specified in lines. 
If one assumes the number of lines to be equal in both/all video-modes the 
font-height would have to be adjusted (by sacrifying quality of the font).

The other way would be to use the currently available number of text-lines 
that the plugin can change its contents accordingly.

Another reason for different fonts required might be different aspect-ratios - 
a 4:3 font displayed at 16:9 looks compressed horizontally i would assume?
