Hi Jim/lists

I have a number of recordings made prior to the demise of Teletext in 
the UK who's subtitles it would be good to be able to show. I don't know 
about practice elsewhere, but, in the UK, Teletext page 888 was used to 
carry the subtitles. Would it be possible to retain the playback capability?
