there are quite a few EPGs available in Australia.  i don't use a D1 box 
but did previously use the D1 EPG since there was a tv_grab_au script 
which could use it.

however, there has been (what i consider to be) a 'better' tv_grab_au 
script available that uses ninemsn data.

note that you probably don't need a 'mythtv-setup' to change this - 
mysql access with phpMyAdmin provides a nice interface to modify things 
in the datbase...

D1 have based their product on something licensed under the GPL.

as such, they are obliged to provide both source-code, their changes and 
instructions on how to build an 'image' that runs on their hardware.

regardless of GPL or otherwise, there really isn't any rocket-science to 
what mythfilldatabase does - i don't think the database schema has 
changed that much regardless of what version d1's code is based on.

but i'd be very very surprised if its on 0.14 - more likely 0.16 or 0.17 
but given they support dvb these days its likely 0.17 or 0.18.


cheers,
