red89mx: Yep agree re teletext......but it was a lifesaver earlier on.

This thread is re captioning on Freeview terrestial channels whish have never been teletext.

Yes and the captioning uses the standard DVB subtitles, along with MHEG5 as a future replacement for the actual Teletext service.

All Freeview certified devices are required to support both. Since the Tivo isn't Freeview certified there are no guarantees it will work fully with Freeview.
