I've gotten the fast ship movement myself. I don't know what causes it. I sometimes have other programs running when I play, though. That might do something.
As for music, the CD music sounds okay, but I'm too much of a B5 fan. I tend to play stuff from that show and a few others on Winamp while I play.
Though maybe "Requiem for the Line" isn't a good mp3 to play when defending a world against an attack.
