Yea, I understand the limitations. TFA mentioned 6hr runtimes (rather than 15.5), which is more manageable. If you WFH I’d guess 2-3 is feasible at least 5 days a week. Of course, if the teletext requires a second run then that’s double time. I suspect any serious archival setup for this will eventually settle on multiple recording systems.
wrt to storage, I hope one is running a reasonably low res for this with some moderate compression. This is vhs after all…
If its only about teletext you dont need whole 6 hours. Teletext loops whole content in around a minute max. It would probably suffice to capture until vhs-teletext confirms full decode, minutes per tape instead of hours. You will only miss live changes - I think there was chat and sport results.
