Like Shawn, I have tried your code in isolation and only get the expected 
results. I looped it over a few test values:

<?php
$valueList = array('"','"test"','"test&test"','"test&amp;test"');
echo "<pre>\n\n";
foreach ($valueList as $value) {
	echo "Before: $value\n";
	$value=preg_replace("%&(?!amp;)%i", "&amp;", $value);
	echo "After: $value\n\n";
}
echo '</pre>';
?>

outputs (ignoring <pre> as that was just to remove the <br /> for easy 
reading):

Before: "
After: "

Before: "test"
After: "test"

Before: "test&test"
After: "test&amp;test"

Before: "test&amp;test"
After: "test&amp;test"

The only conclusion is that something else in your code is converting the 
quotes. Have a look around.
