Hi Wade
If you look at nv17_tv.c it will answer all your questions
It boils down to nv17_tv_set_property()
* if (property == conf->tv_mode_property) {
if (connector->dpms != DRM_MODE_DPMS_OFF)
return -EINVAL;
* if (property == conf->tv_select_subconnector_property) {
if (tv_norm->kind != TV_ENC_MODE)
return -EINVAL;
For a list of TV_ENC_MODE vs CTV_ENC_MODE take a look in nv17_tv_modes.c
Have fun :P
