Thanks for the reply fella,
This has just suddenly got more confusing that first thought :-S
My Parents are now in possession of the box and being in their 80's I need it to be as simple as possible so wanted to flash an image that would be easy for them to use with a nice EPG... I was unaware of flashing bootloaders as well as images... I will try those images you have linked to, I really appreciate your time and will do some heavy reading before I carry it out..
Many Thanks
