Dark_Jedi,
When I look at the 720p sample the only blemish I can spot is when C3PO and R2D2 have their close up shot on the ship you can see the jaggies really bad on both droids... I don't know if it was there all the time or if its something that has been introduced by whatever filters or processes that you are doing to the film but if there is anyway you could improve that shot that would be great...
