--- Comment #5 from GHPS <freedesktop-software at guido-schroeder.de> ---
I can confirm this bug and can see that it exists at least up to Mesa 17.2.4.

Background: Switching from Kubuntu 14.04 to 16.04 I had the problem that
DVD playback in VLC was broken (see screenshot of the Dreamworks Logo "Boy on
Moon"). After digging a bit deeper I was able to locate the bug in 
libvdpau, precisely its MPEG1/MPEG2* decoder capabilities 
[full background story with hardware/software specs:1]. 
This results in the blocky artifacts of vdpau in Mesa 12.0.6 
on a Radeon of the r300 family.

Upgrading my Kubuntu 16.04 system to Mesa 17.2.4 didn't fix the problem.

Tests with Kubuntu 17.10 (released with Mesa 17.2.2) show that here the same
problem is present.
