I believe I did understand what you meant back then, but I would
hate to have to switch my TV into teletext mode all the time.
Besides, I don't know whether TT allows full pixel graphics.
AFAIK it only supports block graphics, which wouldn't allow
for the kind of progress display and editing markers VDR implements
now.

So, if I could choose I would prefer an improved OSD over teletext
any time ;-)
