Maybe it's non-DXVA compliant? Or is it a DVXA-ATI bug?
I have the same card, same drivers and have had the same problems. They broke something and you need to go down to 3.0 levels for it to work properly...

Extremely annoying.

Try the 10.4 preview driver (its an official unofficial driver, that is, from AMD/ATI but not WHQL or final 10.4). There are also one or two beta drivers floating around which may react differently. The drivers below are all straight from ATI, and are likely more stable than the leaked drivers, some of which are apparently modified.

There is the normal 10.3 driver, which is the current mainstream driver available here (http://game.amd.com/us-en/drivers_ca...indows-7-64bit), the 10.3 OpenGL driver (http://support.amd.com/us/kbarticles...ew-driver.aspx) and the latest preview/hotfix driver, released 15 April: (http://support.amd.com/us/kbarticles...-4-Hotfix.aspx)

Despite it claiming it has only one fix, it is likely to contain many more fixes but is released just to provide a fix for the above issue. Try it out the 10.4 preview driver and see if the problem still occurs

Hi burfadel, thank you for your suggestion.
I've tried catalyst 10.4 preview drivers, but the macroblock-bug remains

So, maybe it is a bug that affects 5xxx serie...

Only problem I found was with an old version of VLC Player. Which I only use since it's capturing function isn't broken like newer versions. I usually use newer Mplayers anyway.

Other than that, everything works fine.

Used to work perfect to 4.1 (aside from an odd issue limited it to 11 refs but I think that's a dxva global issue tbh). Something got broken :P

Honestly I'd send them an e-mail because they may not even know about it. In fact I may also later.

I'd guess Terry Makedon aka Catalystmaker would be the person to ask.

The DiAVC produce identical output with JM bit by bit for the two bitstreams.

Same issues on DXVA with ATI Radeon HD4650, Catalyst 10.3, MPC HC r1788 both x86 and x64 builds. It looks like an ATI bug. Also I have another one video with same problem, encoded with x264 r1510 and proper DXVA restrictions.

Both files play fine:

1:
Mobility Radeon HD 2400 XT
Catalyst 10.3
Windows XP SP3
MPC-HC

2.
Radeon HD 4870
Catalyst 10.3b Preview
Windows Vista SP2
MPC-HC

But with Catalyst 10.4 Preview I have the same issues on PC 2. (Didn't test PC 1 with 10.4 Preview).

I'm curious too. I've searched around on Google, found some explanations referring to better motion vectors because you can reference "better frames", but i also found some articles speaking of multi-view encoding.

It's required to make basically any multi-ref H.264 encoder work correctly. This test was just to see if a particularly obnoxious corner case (that we didn't create previously) caused any problems in any decoders.

I'll let up to someone else to go into subject of the meaning of your "obnoxious corner case"

Intel 4500mhd DXVA
WDTV v2
Microsoft Xbox 360

Looks like all decoders work fine with this

The error displayed by the The Ati, must have been the decoders fault, cause it seems to be the only decoder that displayed errors. Also there are different posts in the MPC-HT thread mentioning errors too. So it might not even be related.

Personally: I've just ordered a HD5770, so i do hope they fix the problem
