Give that man a beer!

Much better assuredly.

Pending more learned answers on your last question, I would be wary to 
affirm this. The point being probably - if those are silently ignored by 
method 3 as Alain states - that people will wring themselves into hoops 
only to see some 'improvements' to their media, without any results 
obviously. If, on the other hand, those are /not/ ignored, we need to be 
dead sure about it. What does the code say, Mr Pokorny?
