It does tell you about the not registered components. Btw: which "trick" do you currently use to allow unsigned drivers? If you install all updates the dynamic methods are all failing and only F8 does still work. However according to M$ this will be removed as well...Exception ystem.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
I'd simply sum up: there's no profit running W2k8 for MP's TVService at all therefore your best option is to stay away from it.
