The "line 23"-stuff (WSS) is similar to videotext, but not the same
(slower in speed and signaling). The question is: the hardware and
driver can reinsert the teletext data, can it reinsert the line 23 too? A
grep through the driver directory did not find anything related to WSS. I
guess at least the firmware have to be able to do that.
The pin 8 signalling (6V or 12V at scart cable pin 8) is not possible with
the DVB-S. There is simply no such signal available at J2, so we should
look at that WSS-signal - is there a way to get it enabled in the driver?
