I don't think TESB is notably worse than ANH. The same amount of temporal smoothing is present in both, but it's just more noticeable in the Hoth scenes because of the white background. I did notice side 3 had a low saturation, but it was constantly low, and didn't vary though the side. Line drops were not a problem by then because I'd effectively filtered them out.

When the reviewer mentions "stars" in the black bars, I think he's referring to "specks" caused by small video dropouts.

And his complaint about the cut at the end of side one of ROTJ; it occurs just before Luke jumps off the sail barge plank. No missing frames though (unlike the end of side 1 of ANH) so not a problem when joined to make a DVD.
