I'm still seeing this:
Please note that for the desktop/multimedia Ubuntu Xenial is recommended (and in fact it's the only currently provided desktop release)

"libvdpau-sunxi" column is the current status of what kind of HW acceleration can be expected. As you see, MPEG4 may not work and 10bit H265 will not work too
Removing packages should work fine, it is also possible to customize with the build system. If you have some issues with apt-get remove, it's unlikely a software problem, most of such problems are solved by changing the storage and power supply even if users think they are good enough.
Upgrading server->desktop is possible but is not recommended since some additional build time configuration tweaks may not be included in this case.
