I'm looking to purchase an on-digital box or satellite system from e-bay for FTA viewing. The on-digital box will be easy to install, will the satellite system require a profesional, if so how much does this normally cost? Does the interactive parts work on both FTA systems and is one system more advance than the other? In the Times today it mentions the problems between the BBC and ITV concerning terrestiral digitals future. Has the satellite system a better future? Look forward to hearing from you.
