I purchased an x9s with firmware 2.1. Contrary to previous firmware HDMI IN does not present the option to modify the frame rate and in my case all recording are made at 50 FPS. This force me to use avidemux to reduce the framerate to a more tolerable 25/30 FPS at the expenses of hours of pc conversion. Does anybody knows if the more recent firmware version, AKA 2.1.22, has reinstated the option to modify the recording framerate? Thanks.
