I use both Kazaa Lite and BitTorrent. Kazaa Lite is pretty decent for music files, but it's hard to find any movie thats over 1 gigabyte. That's what I use BitTorrent for

.
But yeah, I downloaded the entire Kenshin series, and when I opened the folder, the files were in some shitty video format called .Ogg; half of them didn't work.
