I guess this is from the same people who watch a cam of a newly released movie with people walking by on the screen, from a 700mb divx, on a 15 inch screen, and who wonder why everybody doesn't do it this way, because I only waited for it to download for 4 hours, and yeah then I had to manually fix the synchronization of the subtitles (which I had to ask around on IRC for for half an hour before I found someone who had it), and oh I did have to install and download a couple of tools to decompress and fix and subtitle and play the movie, but dammit it was all worth it because I saved 5 bucks.
