Indeed I had to switch mice in order to watch Video with MC18, because the previous mouse I was using, had a touch area instead of a wheel, and I would brush against it and the video would jump ahead or back (obviously not acceptable!).
The replacement mouse has a wheel which is stiff enough not to turn without intentional action.
BUT, one could watch MC18 with only a mouse IF there was a little more mouse support in Video, namely:
* Configuration of the mouse wheel action
* Left-click pauses - as MPC-HC does (and I think one other player). The logic is simply " If Full Screen And Control Area is Not Displayed, Then Left-Click Equals Pause. "
The reason you don't need a remote control is that 99% of the time, the only things you need to do are:
* Select Video
* Start Video
* Pause Video when phone or doorbell rings
All of which are easily done with a wireless mouse.
While a remote control is helpful when later you want to go back and see what was that thing in the background of the second scene, most of the time one only does the above...
