I want consistency

[blu1183]

when im watching a movie on cable i can switch the sound field to whatever i want. right now its set on neo 6 cinema. but when the blu ray player is on i cant switch the field, it tells me "not used". i was told its because they want me to hear the BD as it was intended to be heard. my question to you is what sound field should i use on the cable box so its consistent with what i hear on the BD player.
