It is not possible to tell the firmware to change them. There are two documented CX23418 API commands in cx23418.h: CX18_CPU_SET_VIDEO_PID CX18_CPU_SET_AUDIO_PID Unfortunately, I know they do nothing and will always directly return 0x200800ff, which is a CX23418 API error code. Good to know. Thanks! Lars.
