Hmm, no seeders/leechers? That looks deceptively familiar.
Are you using the same ISP at your parents' place? If not, there's a good chance that your ISP is screwing with your connection to the trackers, as you seem to have the same problem across all of the torrents.
The fact that you can download from public trackers (excluding BBT) makes sense because they usually have DHT and Peer Discovery enabled. BBT torrents have these disabled in order to track stats properly.
You may want to try forcing encryption or downgrading your version of uTorrent. I doubt either will help but it's worth a shot.
