This morning, I was downloading a torrent. It was downloading consistently at about 150k/s. It was doing this for about half an hour before I stopped it because NO data was downloading!
My only explanation is that perhaps there were no complete PACKETS.
Another odd thing I noticed was that in one of those lame mega sized collections, many of the videos would not play because they were FAKE! They completed, they had data, they checked. Someone uploaded several bundles of corrupt files along with some other files that did work.
Tbis happens extremely rarely, so it is not a big deal.
