I downloaded it and I'm watching it right now. Overall i like what I see, mostly the colours and the detail.

There were 6 problems I found till now :

- the sound goes very slightly out of sync for a few seconds when Luke speaks to Han (it seems to be 1 or too frames off, it's very minor)

- there are occasional slight shifts to red which "correct" themselves within a second

- there was a weird white error during the Han/princess argument around 6:46 - I don't have a way how to watch it frame by frame - it looks similar like a damaged VHS tape :-) The same thing happens around 16:30 when Luke is in the bacta tanc and around 19:40 and 20:06

- the scene were R2 and C3PO are standing outside and scanning is extremely blue and oversaturated, AFAIK it was never THAT blue before 2004

- the scene were OB1 shows himself to Luke (around 12:59) the space where he will appear has a thick dark blue background which I never noticed in any other version. The same problem appears a few seconds later when OB1's ghost disappears and Han arrives on his tauntaun

- the snowspeeders which are looking for Han and Luke look "animated", they're not very well integrated to the background
