Today I reinstalled Win7 and made a clear installation of MP 1.2.3 with SC 1.0.3
Now there is no MP crashing at 1 minute after video end, but SC cannot start screensaver (after 1 minute, when any video ends, all previous settings).
ScreenControl 1.0.3 installed, all logs deleted.
Windows screensaver set to 30 minutes.
Mediaportal screensaver (idle timer) turned off.
Checked on Power tab:
Enable power control
Activate screensaver after 1 minute
Prevent, if fullscreen video or TV is playing
Prevent, if fullscreen...
Failed to locate assembly 'Micropolis.HDcore" received, when installed from .mpe1 package on Win7 32 prof. HDCore file is really absent in folder.
The resolution is to download a zip package from the first post here, and copy it directly.
Some another problem with MediaPortal 1.2.3 +...
