Good point.
Another "classical" piece from russian cinematography:
Amazon.com: Business romance / Sluzhebny Roman: Eldar Ryazanov, Alisa Freindlikh, Andrey Miagkov, Svetlana Nemolyaeva, Oleg Basilashvily, Liya Akhedzhakova: Movies & TV
Служебный Роман (Business romance), famous ("epic") comedy. With rus. subs.


But how many others can be found on Amazon (or in DVD stores) apart from these ?

Even if you want to get a legal copy of some 1960-s\1970-s movie, sometimes it`s just
impossible to find.

Then go to rutracker [dot] org (like all russians do), register and get a rip of what you want.
You might also need a torrent manager (like utorrent or Vuze) in order to download.

P.S. What I`ve posted in a previous post is a quote from a ".srt" file which should be put at the same catalogue where your video file is. The file can be .avi or .mp4 or anything else. What matters is that the videoplayer you use supports subtitle capturing. I recommend to use Media Player Classic or BSPlayer, since they are very simple.
