vmr9.log should be under log/ relative to the startup directory of mediaportal.exe (depends on your shortcut settings). normally MP should be started within "program files\team mediaportal\mediaportal\", but maybe this is different on your installation?
edit: i think you need to disable DX9 exclusive mode, since this won't work together with EVR yet. usually this should have been disabled automatically, but please give it a try.
are you using any plugins that "mess" with the picture, such as the crop-manager? they are known not to work too.
