The first reason is because FOX chose to only release DVDs for the first six seasons. Thereby necessitating the creation of a downloadable version.
The second reason is because all of the other versions uploaded by out there which I could find were just plain dreadful.
So I made these using the AdultSwim broadcasts. Even as these were made by someone who knows zip about this stuff, I still managed to create files that were incredibly superior to all of the other Season Seven files.
I have included the torrents of my competitors so you can judge for yourself.
Have fun and enjoy!
P.S. This torrent is my first, so be patient with me while I learn this stuff.
NOTE: when FOX finally danes to release Season Seven on DVD, I will take down this torrent... and I will not be held responsible for any Peer Exchange or DHT related issues, because I will cease uploading and remove them my hard drive as well after that occurs.
