The copys that are in this torrent are the best i could find. It is a pity that the source is not a blueray (they have not been released by the way) since it I think it looks the best at about 1,5 GB versions of the blurayrips i have seen like firefly that looks better as a 1,5 GB version then 1 GB version when converted from a blueray. ArcImpuls yes you can make a 750 MB 720p out of a 40 minute show and maybe you cant see a deference on what ever you are watching it on but there is a slight difference that i can even see on my 17' computer screen between 700 MB 720p video and 1 GB.
