Retried some stuff. If i switch my HTPC to 24p hz i can turn on CS on the TV just not at 60hz. if i stream video from my HTPC to samsung 3d dvd player the dvd will switch as needed and if 24 hz i can turn on CS. if i stream from HTPC to tv's media player using all share CS is not able to be turned on with any files i tried, that the DVD player would select as 24hz. maybe that helps? CS needs 24hz to be active.
