I was not previously aware of the "Drive Free Space" plugin, and it is not easy to find. (There really ought to be an easier way of finding plugins.) There is this thread that introduces the plugin, and this thread that details some changes to the Titan skin made by Gary Martyn (from 2013 ).Spent hours trying to get this going just so I could check the difference of including the Drivespace section.
I installed the plugin on my Aorus laptop which is running Windows 10 64-bit with MP 1.33 64-bit. This is what your changes to the "Recorded TV" panel look like. Note that the panel shows no recordings because my laptop does not have access to any TV tuners, and as a result "TV Server Config" prevents me importing any existing recordings from my Dell HTPC.
