So, looks like a driver bug. Let's reassign to mesa, which provides the vdpau implementation for nouveau.

VLC would not display video from HD Homerun Prime network tv tuner with latest firmware (tuner works on different PC). VLC also failed to display video from DVD. Audio worked for both tuner and DVD. Completely removed VLC using Synaptic including configuration files. Installed VLC from Ubuntu Software Center, which installed a SNAP version of VLC. The SNAP version of VLC would not run. Uninstalled VLC using Ubuntu Software Center, installed a different VLC version from Ubuntu Software Center (probably non-SNAP). This version of VLC again will only play audio, not the video from DVD or the hdhomerun_config_gui.
