Hi,
I noticed I can't access any DRM content via Silverlight, so long as my Intel HD graphics driver is installed.
Have tried just about everything so far and have been googling the issue for ages - with no reuslts. The only answer I could find so far is that this seems to be an issue with certain graphics drivers for which there is no apparent solution yet.
I am using a Lenovo ThinkPad x230t (34372YG) with an Intel HD graphics 4000 chip and all the latest drivers and updates.
I have tried reinstalling/repairing the Silverlight installation multiple times, have reset the DRM cache, tried to stream content in various browsers (as administrator) and with different internet connections.
The only thing that seems to work is to uninstall the Intel graphics drivers - at least until Windows automatically installs the latest drivers, at which point it stops working again. So no real solution there, either.
This has become really frustratin, since I can't use a single Silverlight-based online streaming service from this machine.
Any help would be appreciated!
Thanks,
John
