Here's the first vid. The source file to get this was the center channel of the AC3 file, so compare to that mono track and not to the complete audio if you wanna hear what was lost, specially SFX-wise.
Do you see what I was trying to tell you before about the voice may become hollow or boomey?
It's a good effort and you have not done anything wrong but you can clearly hear where the frequencies you have removed also have removed part of the voice making it sound hollow because the soundtrack has clashed with the bottom end frequencies of the voices and a couple of times sounds boomey where you cut the top end.
Because the frequencies you removed also are spanning a broad spectrum and changing it's creating a phasing effect too.
repeating this process in another program might get you slightly better results but not by much.
It's a cake and you can not pick the sultanas out of it... you can slice it but whatever you decide to cut out of the cake once it is gone it is gone from the cake.
so the sultana you wanted you had to slice it out the cake but in the process you cut the sultana up also.
It's pretty much impossible to cut the sultana out the cake unless whats around it that you want to cut is also well away from it in frequency i.e. distance
