50 Minutes Inside, a French television show, broadcast new footage from Half-Blood Prince.  For now just a description is online:

Lavender calling Ron ‘My won-won’, Hermione bored of Cormac, Ginny giving some cake to Harry at the Weasley’s house, Ginny stealing the HBP potion book and asking who is the HBP? Some news scene from Quidditch and some more actors interview Daniel, Tom, Bonnie, Jessie, Emma, Rupert.

Thanks UHP.
Update: The video is now online!:
