No longer able to record video in VR with HP Reverb G2 and WMR

A while back it was possible to record 5 min clips in VR by pressing on the home button on the HP Reverb G2 controller, which would bring up the WMR context menu in the sim, and from there I could record 5 min clips.
But after the latest updates, things seems to work, but the mp4 clips that actually get recorded are only 1 second long.
