Installing Rollup 2 seems to have introduced the following 2 problems:

1. Using settings to set my speaker type to 5.1 and connection type to SPDIF
no longer works reliably.
Sometimes when pressing TEST it works ok, most of the time though it
only outputs stereo.
Even when the test works it will not work subsequently with a DVD.

2. The system will never go into standby automatically after it has woken up
to record or after 10mins of inactivity as defined in the power management
settings.
have stopped the Extender service as suggested on the Green Button forums.

I am using the latest version of the NVIDIA Purevideo decoder & a
Soundblaster Live soundcard.

Both of the above worked perfectly before Rollup 2.

Any help will be much appreciated.
