Query: the series

it's a very good series.so,I'm going to review the set itself.a couple of the discs skip or freeze,they didn't seem to be dirty,could of been my player.the set comes with the movie "razor",so you don't have to buy it separately(yes ,I bought the movie when I bought the set).Here's my main gripe,season 4 starts with "Razor",then disc 2,3,4.there's no disc 1... disc 2 starts with "previously on battlestar galactica" there's couple of scenes from episodes I've never seen,and that first episode on disc 2 seems to jump forward a lot.So I really believe they left out disc 1.Someone that knows the series better than me will probably correct me on that,and that okay 'cause I'd like to know.All in all,it's a really good series
