Small issue with the OP video

[dilworks]

Don't know if anyone else has noticed this, but there is a nice teaser video that plays if you leave the title screen idle for a while. However on my case, the game shows a BLANK display where it should be the video (the sound track plays just fine - I can hear the lyrics, etc).

However, if I play for a while, then exit to the title screen, the video now plays just fine! WTF is going there?
