crap sound quality

hey guys,
i need help!!!... when i use my mixvibes DVS mk2 program simply just as a music player at home its sounds great!!!!
BUT!!! when i got to a gig and set it all up properly with my turntables etc, all i get is a crap popping/crackling sound!!!
it sounds bloody terrible!!
originally i thought it would have been my cartridges/stylus,
but then i pulled out some old records and there is no problem playing them!! so the needles arnt to bad!!
then i asked my computer wiz mate to help me and he suggested to download a sound driver!, i done that and i still have the same problem, but i think it might have improved a little as i was able to play atleast 2 songs with mixvibes at my last gig....
if any one could please help me with this problem it will be really appreciated!!!
thank you!!
