Unplug your RGC Device and put it aside until you are finished.
Download and install the Revo Uninstaller (select the free one). Then run it in Moderate Mode to remove any traces of Roxio. Then turn off your Anti Virus, Firewalls, Registry Cleaners. Now insert your Roxio Disc. When the Install has completed turn your AV & Firewall back on and reboot.

So the Roxio Capture card and the HDMI cable are OK, that leaves the MHL Adapter.
Try connecting your phone>MHL Adapter>HDMI cable directly to a TV/Monitor (Hdmi input). If that works hook up the splitter and make sure both outputs work.
