I believe this should be possible, since the OSD can draw bitmaps
(and the teletext font would probably have to be drawn as such).
And this definitley woud be a much faster solution since re-insertion
would have to go through the same bottleneck as normal videotext,
so any speed gain the PC would be able to make by caching all pages
might be mostly lost.

However, even with normal fonts the current OSD is pretty slow.
I guess it would have to be a lot faster to do a good job with
teletext (and of course VDR would also benefit from a faster OSD ;-).

Ralph: any chances the OSD can be made faster?
