Windows Media Center Extender encountered a DRM failure

[amallon]

Hi,

I'm getting a DRM error in eventviewer. This happens when I'm watching recorded or paused tv through my xbox extender. Watching live TV never gives any bother. I'm running 64 bit Windows 7, from an SSD. Recorded TV is on a 250GB Sata drive. Its a Core i3 with 10GB RAM. The network connection is Cat6, with a Gigabit switch

When watching recorded tv the program will freeze, you have to hit stop then resume the program again and it will play fine. The event viewer message is displayed below.

Cheers
Aidan
