They look lovely on my normal sized (25 inch) TV, much better than the laserdisc transfers I had before as far as overall detail.
The only problem I have is when viewed on my mom's huge bigscreen TV, some of the the Tatooine scenes in ANH and Hoth scenes in ESB have a distracting amount of what I'm assuming is film grain.
I never expected them to be perfect, but I was hoping for a cleaner transfer from a better source (and making them anamorphic wouldn't have hurt either)
