The logo is only supposed to be visible in the mirrored view, never in the headset. That works as intended here with MPC-HC, which vorpX normally hooks directly. I’m not sure how that would even be possible ATM, but I’ll check whether there may be circumstances where it may be shown in the headset.
If you want to watch movies on your monitor instead on your headset, you can simply disable vorpX or pause the vorpX watcher (right click the vorpX tray icon and choose the according option).
