I also use infocus 4805 krub. Once I bought Soken DV-971 and I was very disappointed, picture quality is not good, build quality is not good (look very cheap), doesn't have disc resume function, cannot use progressive scan through component (not even 480p). As a result, I exchange it with Samsung HD850 within 1 day (I am very lucky that I bought it from the power krub, I can exchange it without any trouble). Now i am very happy with samsung krub.
