Having lost its slot on Freeview, Five HD debuts on satellite and cable TV today.
The new channel will be available on Sky HD and Virgin Media, and will broadcast a simulcast of Five's standard-definition schedule, including "a wide array of programmes made in high definition" (which suggests that not all of them are).
Five's brand-new live entertainment series Don't Stop Believing premieres in HD on Sunday, July 18th.
Other programmes to be shown in HD include popular Aussie soaps Neighbours and Home & Away; US dramas The Mentalist, Grey's Anatomy, Law & Order: Criminal Intent and Law & Order: Special Victims Unit, as well as sports coverage from Cricket on Five and Europa League football.
As well as Five HD, Virgin is also adding two new time-shifted channels for Fiver and Five USA, to be dubbed Fiver +1 and Fiver USA +1.
