Update2: 7/23/2011: Season 2 is now in order. Seasons 1 and 2 are in a new order, and we’re currently working on the new order. Be careful when watching Seasons 1 and 2 until we get the new order posted.
The first and second seasons of The Tudors have been giving everyone a lot of trouble lately, not because we have any trouble figuring out the order, but because it has changed 3 days in a row. On 7/16 we updated the order that has presumably been changed before that, then it was reported to have changed on 7/17, yesterday, with even a new episode missing in Season 1 (#7).
It was just reported via anonymous comment that the order is wrong again today, 7/18. I will get to work finding the right order as soon as I can, but please bear in mind that Netflix is doing something behind the scenes here, and you need to be very careful watching episodes as it may be the wrong one and contain spoilers. Keep us posted in the comments for each season with any information you find out as to the right order.
