However, the new head of BBC HD aims to change that.

Danielle Nagler said: "Hopefully we can push people in the right direction. We try to offer viewers the best of the BBC's HD programmes, so I have got the job of cherry-picking from all the BBC channels to create the best possible showcase for HD content."

The London-born 35-year-old - the daughter of former Board of Deputies' director general Neville Nagler - gained a first in English from Cambridge University.

A former FZY leader, Danielle joined the BBC as a journalism trainee in 1996.

Mill Hill-based Danielle recalled: "I presented the news for BBC Radio Solent, which is based in Southampton, and I also used to read the bulletins for BBC Radio Two, Three and Four and reported for the Today programme."

Danielle met Liverpool-born husband Jonathan Wolfson while they were students at Cambridge and they married in 1998, with the aufruf held at Childwall Hebrew Congregation, Liverpool.

They have three children - eight-year-old Naftali, four-year-old Eliana and Sigal, 10 months.

Danielle headed the BBC Project Team working on Charter Renewal with BBC Two controller Roly Keating and more recently worked as head of the director-general's office.

The BBC HD channel launched in December and broadcasts five hours a night during the week and around six hours a night at the weekend.

Danielle is encouraging people to get HD, as the picture quality is excellent.

She explained: "Certain genre of programmes look amazing with HD, particularly sport, wildlife and drama - you really lose yourself in the experience.

"We have also had concerts and music programmes on HD and we are going to broadcast the Proms and the Electric Proms on the channel too."
