Still I think it would be more consistent to be able to start recording via trigger, too.
I usually don't save the whole buffer, so I'll walk to the camera in between shots anyway. But it's just not intuitive to stop recording by remote trigger, walk to the camera to safe the file, start recording on the camera, walk away, do whatever I want, and stop recording remotely. If I want to redo the shot, but already triggered the camera, I need to walk up to it and start recording, even if I have a large button right in front of me.
I'll be much more intuitive if both triggers worked the same.
