Most video recorders ISTR didn't record the Teletext info although you could get recorders that did IIRC.

Most of them recorded Teletext data, they couldn't help it unless they blanked the VBI. Whether it was possible to reliably decode the data when played back was a different matter, due to poor recovered eye-height.
Standard Play VHS was tantalisingly close, and the header row reproduced reasonably well (because of additional error correction) but the body of the page, if it appeared, at all was usually full of errors.
s-VHS could give results
I never tried Betamax but its faster writing speed and resolution may have pushed in the right direction.
Some VHS machines
decoded the teletext internally, so it could burn in 888 subtitles, and make use of the programme schedule pages, but that's a separate matter.
