For my collection of a.d.u.l.t films, I have built a system that allows me to create previews of my favourite ones. I take the snapshots myself (to capture only the best moments), remaster the snapshots by removing all artefacts from them to make them really pretty, and finally create one big image containing up to 70 frames of one scene. Packed for maximum pleasure in high resolution :)

No. There is enough a.d.u.l.t junk out there that kids can get to without any problems, I won't add to it :) However, I don't believe that you would be disappointed with my previews - at least not if you like that kind of eyecandy...
There are a few very interesting and high quality sites that I can recommend for information retrieval and eye candy:
A.d.u.l.t DVD empire
Giant IMDB-like database for actress and film info.
The best p.o.r.n
The best review site around with 4 reviewers for each item.
I am constantly updating my previews collection, so I will add any new links here as soon as they are available. They will be marked with a green NEW sign.
