POKER INFO - PROILE - Daniel Negreanu

Am I crazy or did Daniel possibly get screwed by a dealer error at a WSOP final table? I only saw the show once but I swear that the dealer burned twice on the hand where Juanda knocked him out. The dealer was burning when Juanda stopped him to go all in before the river. Then the camera was above the dealer as he burned and turned the black 5. I am fairly certain that I counted a total of 4 burn cards tucked under the chips. The 4th burn should have been the river, not the card we all saw. Can anyone else verify this?
