VLC currently uses xdg-screensaver (from xdg-utils). At some point, it uses X11 screensaver reset also, but it hit a performance bug in a number of Xorg drivers, so it had to be removed.
I don't know any other FreeDesktop/standard way to inhibit the screensaver and the display blanking.

So my guess is that xdg-utils is buggy in Ubuntu.
