The nhance3 300 movie rip is not 5.1.Its AAC,with 2 Front and 2 Rear speaker seperation only which sucks.If possible,get the 1080p version of 300 released by HV with DTS audio.The quality is just incredible.A 720p 1 1/2 hr movie is usually arnd 4.3GB and in case of a longer runtime and DTS audio,then its arnd 8GB ala Transformers rip by hV.Esir,CtrlHD,Refined,hV,Sinners,Reveille,Septic and off late Chakra are all usually gr8 quality.
