Virgin Media TV customers can now watch a range of BBC HD programmes, including Robin Hood, Friday Night With Jonathan Ross and Later...With Jool Holland, on demand via the iPlayer.
Upcoming HD highlights will include the two remaining Doctor Who specials and the new series of Dragons' Den.
Katharine Burns Rivington, executive director of content acquisition at Virgin Media, says: "BBC iPlayer has been a huge success on our TV platform and we're thrilled to be expanding the service with HD content.

"We're looking forward to increasing our line-up of broadcast HD channels over the next few months and combining the best of HD and on-demand TV."
Last month Virgin announced that series 3 of Dexter would be available in high-definition on the company's TV Choice on-demand service, and a selection of HD content from ITV Player is available on Catch Up TV.
