anyone here got any tips for 2nd RC video? it's been a while that I used the 2nd RC. the video out from it is unusable. looking at 1 fame per 1-3s that is actually not corrupted. most of the time it's just grey out. I tried every single channel from 13-20 manually, turned off OSD and dual output to HDMI. currently on NVidia k1 for both remotes, 1 with 4G sim and the other is wifi only. and on 1.1.0 app, firmware 1.2.1.03. video to 1st RC is fine, but the 2nd RC is unusable. it is almost as if there isn't enough bandwidth or something. when I tried with manual channels , I even set the bitrate to lowest, but its of no help. anyone experiencing this issue where 2nd RC is useless?
