I used version 4 on my last set,and to me it looked good on my 65" HDTV being upconverted,I did not like the way the latest v6.64 looked on my setup,v4 looked better to me,maybe not to others,but it did to me,I do not stare at still frames and judge all my work on them alone,yes they do show a lot,but I am all about the motion video,I want to see it how I am going to be watching it.

The version I am using when I redo the set will still be version 4 again,but with subtitle changes and added the ESB fix into it,if g-force shows something different than v6.64 before I start my 2nd set of version 4 then I will certainly test it out,but for right now I am going ahead with what I have.

hopefully that cleared it up for you.
