Grandia II

[Kyusaku]

Im playing using with disc 1 , suddenly, a message like this appeared when i was playing "please insert disc 2 to watch this fmv", but, the message quits after some seconds and everything continues like normal (except for no fmv display,of course). I tried opening the DC lid and placing disc 2, but the screen went black and the DC Options screen appeared (ya know, VMU , Start Game, etc).
Anyone knows how can I watch this fmvs? (i think they're 2)
I tried saving before the fmvs appeared,but thats not possible,since there arent any save points.
