I think its a combo of non 1:1 pixel aspect and 16:9 video aspect. SD DVB 
has 720x576 which is 1.25 aspect displayed on a 16:9. I suspect ATSC doesnt 
have this limitation. so perhaps I can guess most people might refer to 
those using ATSC.
Note I dont think we had as much of a problem with HD DVB 1920x1080 as this 
has 1:1 pixel aspect ratio. not that I use this mode much.
the horizontal font scaling previously used doesnt work with most fonts as 
they only have 1 charset. the default freemono probably does have a narrow 
charset in the same fontfile which is why that one probably works ok.
