A couple that are also great of Doc's are the 2 Rare Performances DVDs which are in the same series as the ones you mentioned (the 5th is Doc with David Grisman which I haven't got yet). A lot of the same guys in the Guitar Jam DVD are also in the Tony Rice and Friends DVD by the same company (also Legends of Flatpicking Guitar has Doc, Tony, Norman Blake etc.) Lately I've been finding these for download on different torrent sites (mainly demonoid)
