It is much easier to download these video lectures from

BTW, thank you for the link! I enjoy these lectures a lot!
Haven't tested with youtube yet, but Infox lectures where english speakers talk have the original sound in one channel and the russian translation in the other channel, so you can actually disable the one that you don't need. I use Core player for that on my Windows Mobile smart phone.
