Please provide _samples_. There are two specifications for teletext
in VBI, this might be the other one, but I have so far never been
able to find samples for this other format and thus MPlayer does
not support it (assuming it even exists, and this wasn't just added
"just because" and maybe doesn't even work).
And yes, I am talking about teletext, I know what teletext is and how
it differs from subtitles.
