This is Entourage S05E10 , which has been compressed using Xvid thus preserving its quality to a greater degree while reducing the size to 1/3 of orignal.
(Ps. its tru tht there is no such thing as lossless compression... but still loss of quality compared to total compression is very low.)
Do check it out and seed.
Compression method used here is similar to the one used by polish rippers xvid asd.
