I see a bit of noise in the sky of that last shot. It's not bad, but I can't help but ask since you seem to be wanting the most out of the movie picture quality itself: have you tried doing "averaging" of multiple capture passes (via avisynth)? It is a bit of trouble, but especially where you're doing things like resizing the image, it is a nice improvement...although this method applied to a whole feature might prove too work intensive (but you can darn near reach DVD quality when you can pull it off correctly from what I've seen, assuming your capturing set-up is pretty good in the first place of course). If you've never tried it, I recommend giving it a go on really small clip capture so you can see the difference (especially when you zoom in). :)
Edit: Sorry, I see now that you don't seem to be doing the captures yourself. Nevermind. :D
