[Dan Rutter]

I think you played this flop well, by betting out, you just got unluckly the 4 came on the turn. On the flop you got the exact situation you wanted, someone( actually two people) with two pair, who would not give you credit for trips, because you bet out. They believe that is an automatic slowplay situation, and think that you would think the same. On the turn after checking, and having it raised after the bet you have to lay down. Even though you just made a full house, your hand is very likely in trouble. With you calling you could have easily been trapped for even more bets, had the bettor on the flop re-raised.
