In "Man of Constant Sorrow", "Verse" lesson, at about 2:31, you say "DUD" on the D. It looks and sounds to me like you are playing "UDU". First, am I mistaken? Second, does it matter? Other than getting the timing of the (what I think is) 16th note strumming.

Also, is your D really a Dsus2? You keep saying D, but the tab and your fingering look like you're leaving out the high E.

Thanks.
