@Bempel:
I suppose you are using HW maker. :)
If you do, I suggest you download the latest available version (RC3) as the previous versions had some bugs.
Now, if you use HW maker but you don't use HW launcher (aka HW BSplayer Autorun), you can deselect the checkbox on the up-right in the autorun tab.
The following text of your bsi file isn't necessary if you do not use HW launcher (as BSplayer ignores it) :
[Autorun]
Language=English
HideBanner=0
Resolution=800x600x16 <---- This line should be in [options] to work!
CloseLauncher=1
OlderVersionWarning=0
ShutDownWindows=0
WithExtras=0
WithPrograms=0
