[Hellcat]

Hmm.... I think I know what that might cause....
If that's it it would reduce the ratio, but increase compatibility....

[EDIT]
OK, try this:

In my above posted code, find theese two lines:

$output = str_replace( "\n" , "" , $output ); 
$output=preg_replace('/<!-- .*? -->/', "", $output);

and replace them by those:

$output = str_replace( "\n" , " " , $output );
$output = preg_replace('/<!--[^\{]*?-->/', "", $output);

Like I already said, this drops the ratio a bit again, but should raise compatibility.
At least I could confirm this in my last tests....
