Right now if Hybrid goes down (or they decide to stop supplying you EPG), your TiVo HD will become a useless brick about a month later regardless of which PROM is installed.

While we think we can provide guide slices to TiVo HD's, we have not worked out how to supply the Spigots to keep them running month to month. As far as I am aware, no one is currently working on this either.

It was decided by us for various reasons not to discuss anything to do with the details of Australian PROM hacking on public forums. I'll Pm you.
