There are two sizes specified in teletext: normale and doubleheight.
By the way: the placement 1/3 from the bottom in the transmission is
without doubt intentional and choosen by the broadcaster to avoid
overlaying the logo and text at the bottom . Very common behaviour.

Don't.
Grab all, store all, and on playback make a dynamic list of any page you
see. Let the 't' key toggle between all options from that list and 'no
subtitles'. Ready, usable, and no configuration/storage needed.
For 90% of the shows in europe there is only one subtitlepage per show anyway.
Other thing: a day-one introduction in C to avoid confusion:
*p++ = 0;
// post-operator, means store 0 at address 'p', add one to p
*++p = 0;
// pre-operator, means add one to p, store 0 at address 'p'
Code as given parsed and displayed all BBC teletext pages correctly, with
page 888 hardcoded on playback.
