Additional problems for ONdigital were the choice of 64QAM broadcast mode, which when coupled with far weaker than expected broadcast power, meant that the signal was weak in many areas; a complex pricing structure with many options; a poor-quality subscriber management system (adapted from Canal+); a paper magazine TV guide whereas BSkyB had an electronic programme guide (EPG); insufficient technical customer services; and much signal piracy. While there was a limited return path provided via an in-built 2400 baud modem, there was no requirement, as there was with BSkyB, to connect the set-top box's modem to a phone line.
