Hi Nietsk,
it is a D7/9 chord:
String + Fret
E: x
A: 9 (3rd, F#)
D: 10 (7th, C)
G: 9 (9th, E)
b: 10 (5th, A)
e: 10 (root, D)
The video lesseon was published in the February 2008 issue of GuitarTechniques (from England), a special issue on Rock´n´Roll. You can still find it. If not, just drop me a PM line.
