I didn't notice any adds but I only use torrents very occasionally, when I'm not at the school dorms.
Anyway, just for fun, I took a look at ESB v1.0 after not having seen it for ages and man is it bad; not only are the black levels pretty bad and there are some color issues but I think I'll have to redo all of the despecialized shots from scratch. Looking at it brought back a lot of memories - some of the shots that seemed so difficult back then would now take me like ten minutes to despecialize and make them look a lot better than they do in v1.0 - some of course will still be difficult but I'm confident I can do a lot better job on those too. I can't wait to get cracking on v2.0 of Empire. I have my last exam of this semester tomorrow and after that, I expect to be done with SW v2.5 quite soon and then I can start on this :-)
