Teletext playback requires a timebase corrector

摘要

I read with interest Geoff Nicholls' letter to Mailbag (October 2008), stating that Allan Hughes was NOT correct in claiming that no videocassette machine couldrecord undecoded teletext subtitles, or words to that effect. While that is indeed true of S-VHS recorders, the story is not that simple. It is the playback that causes the problem irrespective of system bandwidth.
