The new battlestar galactica dvd's (S1, S2.0, S2.5)-- almost all have some scenes that are grainy, is this intended? or a defect? is it to show the gritty nature of the series? I ordered mine through an online retailer and hate to go to the trouble of packing them all up and exchanging them through the mail. I might get the same grainyness all over again if this is part of the intended effect of the show. Thanks for anyone who knows about this and can help answer this.
