Hi Matt,

first it might be easier to just use split here --

$fields = split("\t",$line);

.... I say might because I suspect that the records you have that are
converting incorrectly perhaps don't follow the tab convention? ... said
another way, I've never seen preg break because the file got over a meg
in size;)
