It's possible to get rid of all the startup videos with a simple parameter.
Create a shortcut to _msr.exe
Right Click the shortcut and click on properties
At the end of the 'Target' path add "/NOINTROVIDEO" (without quotes) after the file closing quote. (e.g "C:\Program Files (x86)\LEGO\Stunt Rally\_msr.exe" /NOINTROVIDEO)
Parameters are combinable with the others
Handy because the LMedia intro takes forever.
Another one to enjoy.
