New Freeview Channels

Now that we are beginning to see the addition of new "Freeview only" channels, what is required to generate corresponding guide data for Tivo use? Up until now the only extra channel has been sports extra (with V8's, which I tend to just watch live anyway) so it hasn't been an issue that there was no data.

I assume that the most productive method is to use the EPG which is streaming from the satellite? Given that I don't own a PC DVB-S card I have no idea what is involved to do this, but I'm willing to help any way I can.

Edit: Looks like data for the new channels is now being added - thanks again to the epg gods :)
