VDPAU: MPEG-4 ASP Garbling/Corruption

Created attachment 89489 Playback log from mpv-player
I initially reported this over at the FFmpeg Trac, so just in case I accidentally omit to mention something I've already considered (or just for reference), that's over at https://ffmpeg.org/trac/ffmpeg/ticket/3138
== Relevant Software / Hardware: ==
- AMD E2-1800 APU (/w Radeon HD 7340), i.e. PALM
- Linux 3.12 (Distro: Arch)
- FFmpeg 2.1
- mesa, mesa-libgl & ati-dri 9.2.3
- mplayer r36498, mpv 0.2.3 & VLC 2.1.1
== Summary: == Some files encoded into "MPEG-4 part 2" (seemingly, those using GMC, if zgreg's hunch on #radeon is anything to go by) render/decode incorrectly using VDPAU hardware-decoding on my AMD chipset. The files work fine using software decoding, and worked fine back when using Catalyst & VA-API (which should mean that the files and the hardware are fine).
By "incorrectly", I don't mean complete garbage. About half of the image renders fine, it's just that between reference frames it progressively garbles into a bright-green mess in heavily-updated areas. I'll try to catch a decent screenshot demonstrating this when I can. In the meantime, I've put a sample affected file up on my Dropbox account: https://dl.dropboxusercontent.com/u/3219541/harlock-ep20.mkv
I'll re-attach here some mplayer/mpv logs, and some output from vdpauinfo and ffprobe; and I'll also attach output from glxinfo. If there's anything extra I ought to provide, please say so :)
