To bypass the logo videos & start at the main menu, add -nointro to the command line options in Steam.

Right click on the game in Steam & select Properties from the menu.
In the window that opens, select the General tab & click on the Set Launch Options button.
Another window will open. Click in the text area and enter -nointro.
Click the Ok button, then click on the Close button.

The game should now go straight to the main menu, bypassing the logo videos.
