ATI Radeon X1600/X1800/X1900 MPEG-2 Ghosting/Smearing

AberDino · 2007-01-14, 11:00

In October 2006 I upgraded my Media PC, and as part of the upgrade I bought a Sapphire ATI Radeon X1600 PRO HDMI. Not that I'm using the HDMI output capability yet, as I'm still using a SD widescreen CRT. However, consider it future proofing

.

I noticed straight away that in some scenes, there was a clear ghosting/smearing effect, as if the graphics card wasn't refreshing properly. For example, a dark scene with a lighter object moving across the screen would leave a trail behind it.

After quite a bit of troubleshooting I found out that it was only happening with MPEG-2 encoded material. Next step was to try the various software decoders to see if it was related to that. The same happened with the nVidia and Cyberlink decoder filters, so that ruled that one out.

Disabling hardware acceleration did help, but in my opinion not a satisfactory solution so searched the web for more advise. Eventually ended up on the ATI website, knowledge base article 737-22814. Even though this article seems to suggest it's only relevant to Catalyst driver 6.7, I can confirm it is still relevant even with Catalyst driver 7.1. It seems to affect Radeon X1600, X1800 and X1900 products, but not on all systems. Simply adding an additional registry entry 'TRDenoise' solves the problem, and what a difference! So, if you recognise the symptoms I'm describing here, then please have a look at this knowledge base article for a full description of the solution.

Is it just me or does the link not work ok?

Thought that might happen, hence why I included the actual knowledge base number. If you go to http://support.ati.com and search for 22814 it will come up.

Thanks for the tip. Works great!

In your search for the solution which software decoder was best in you experience with the ATI 1600?

AberDino · 2007-02-07, 09:40

Hi yvos,

I'm using the Cyberlink v7 decoders that come with the PowerDVD Deluxe edition, and combined with the 'TRDenoise' registry hack I am very pleased with the picture.

yvos · 2007-02-08, 07:25

Ok great I will try them.

Hi all,

I'm going to reinstall windows xp, and new ati driver, but I lost the "TRdenoise registry hack" tool, so someone can upload it?

Thanks
