Well, this is kind of an old thread, but I'll respond anyway, because its something I know a fair amount about. I'm very into Russian women, so I've been following the topic for years.In terms of traditional DVD porn movies, Russia doesn't have a huge industry in this regard. The major Russian porn company, who's name I forget, has a US distributor called Brave Entertainment. You can find their stuff through Excalibur, Gamelink, etc, as well as by VOD. Here are there websites:

I've seen a few movies from this company before, and while the actresses were beautiful, I was pretty disappointed with the quality of the videos.
As with so much in porn these days, the best stuff (including video) is often being released via the web. One of my favorite producers is Grigory Galitisin, who was the original photographer for MET-Art before striking out on his own. His site, Galitsin News (http://www.galitsin-news.com), has some absolutely lovely young models in a mix of softcore and some hardcore solo and g/g videos and photosets.
Some other sites that are Russian and Ukraine based Angelfuns (http://www.angelfuns.com/) (mostly softcore) and Harry's Babes (http://www.harrysbabes.com/) (mostly hardcore). Russia and Ukraine also have a lot of freelance web content produced, so a lot of Russian stuff turns up on the many websites that buy their content elsewhere. SapphicErotica was mentioned above – if you search that site for models like Cindy, Angelique, Charlene, and girl they've appeared with – this is all Russian porn.
More generally, Prague is the center of the East European porn industry, and the models working in the Prague studios come not only from the Czech Republic, but from all over Eastern Europe, including Russia and Ukraine. Sites like Denys DeFrancisco's various sites (eg, http://www.1by-day.com/), Paul Markham Teens (http://www.paulmarkhamteens.com/), and several others are all Prague-based and use a number of Russian models. My favorite of these producers is Sweet Photography, who pretty much exclusively releases stuff through ATKPremium (http://www.atkpremium.com/). His videos are knock-your-socks-off good, at least by my standards – some of the best porn I've ever seen.
Anyway, hope this helps,
