Ah, ok. Sorry, I've not been watching anything you've written about

I have no idea what DVB-s stuff works with the full SI information, but
certainly a lot of DVB equipment won't, which is why they are doing such
extensive (slow) testing.

Ah, I didn't realise you were talking solely about DSAT. As far as I
know, provision of EPG over DSAT is out of the control of the Beeb -
certainly on BSkyB CA it was, I don't see any reason why it would be in
their remit now. I'm also not sure how DVB-s multiplexes; with -t I
think the EPG is a full broadcast per-multiplex. I doubt there would be
enough bandwidth to do that across the -s system, due to the sheer
number of channels, but I guess that's speculation.

Providers of a proprietary EPG via DVB-t.

A recorder with a digital tuner, rather than analogue - i.e., something
which saves the broadcast directly. Most free software VRs are PVRs,
although you can get digital tuners.

Probably, but it's irrelevant for this (BBC use uplinks for many, many
things). The Astra uplink would be sent by the BBC themselves, but the
Globecast bods I know will also be uplinking to Astra so would probably
have a good idea about the EPG situation.

Chicken and egg, though. The BBC do tend to supply before the demand is
there as a rule, although EPGs might be a touchy area.
