Actually, the colour buttons are there (use 8300DVB) but you need to manually allocate them - go into Customise for whichever activity you name it (eg Watch Virgin Media) and then allocate the buttons accordingly (ie Teletext Red is noted as 'Red').
There doesn't seem to be a Home button though, so I programmed that one in. For Menu I allocated 'TV Drive' (ie same as pressing V+).
Works fine
