I mistakenly thought DVB-S was using MHEG-5 for the guide info until i was set straight, which led me on a google hunt. Stumbled on to this link this link:

Freeview NZ has adopted the MHEG Interaction Channel from D-book 6.1 allowing hybrid services to be provided on the platform.
Freeview NZ has used MHEG since launch on both its satellite and digital terrestrial services.
Tim Diprose, Technology Manager with Freeview NZ, says, "We believe hybrid IP and broadcast TV technology is the future and is also relevant right now. To have high bandwidth HD mainstream shows broadcast via DTT and niche, catch-up and other on-demand content delivered over IP really makes sense. The New Zealand government has announced plans to roll out ultra-fast broadband to 75 per cent of New Zealanders and this will further support these hybrid platforms and applications."
The MHEG-IC gives access to streamed on-demand video content in addition to traditional text and graphics as well as the ability to support secure transactions.
Diprose says, "By deploying the MHEG-IC we enable a more diverse range of viewing options available on the platform and therefore encourage more consumer uptake. It could enable viewers to easily and comfortably catch up on shows they've missed, watching on-demand on their TV in the lounge (not from their PC) retaining show/series loyalty and viewership, providing broadcasters with new revenue opportunities."

This sounds like what Tivo NZ is doing today?
