I have the following setup:

- Gigabyte MB with 880G chipset (ATI 4250 GPU onboard)
- 2 GB RAM
- AMD X2 245
- Windows 7 Enterprise 32 bit

System is connected to a Full HD screen, and throught optical out to an A/V receiver.

I am encountering the following issue:

running 9.11 Camelot, everything runs fine, CPU usage is between 40% and 50% however.

Running Dharma b3 (and b2 also) I can see a stutter every second when I playbacl a 1080p movie. I use as reference file the intro of the A-Team movie, and in the first minute there is a scene where you fly over the desert. On 9.11 this runs very well. In 10.0 b2 and b3 I get a stutter every ~1 second. I have used the "o" option to check id dxva is enabled, and it is. CPU usage is as low as 2-3% peaking to 8-10%. But, as I siad with a "stutter" every ~1 second.

Things I've done so far.

- Installed almost every release of the ATI Catalyst drivers
- Played with the different video settings in Dharma
- checked/upgraded BIOS and checked CCC settings

I don't have a clue where to look further, maybe someone else has. I will try to provide a debug log asap.

Thanks!
Erwin

Just did a quick check of the debug log, and see a lot of these messages:

They appear every 2-3 seconds, consistent with the stuttering I experience.

i have also the same problem!!

Could one of you please pastebin a full debug log? Also, a sample would be helpful. And could you try disabling dxva to see if the issue is still present?

The pastebin is here:
http://pastebin.ubuntu.com/515916/
(couldn't get pastebin.com to work, links didn't work)

Disabling DXVA makes it worse, pastebin is here:
http://pastebin.ubuntu.com/515919/

I did some more experimenting, and found out that if I transcode the .mkv into an m2ts, playing of the movie goes a lot better.

See the pastebin of that here:
http://pastebin.ubuntu.com/515920/

I will see if I can make a sample of that movie, need to find out how that works as I have not done that before.

Let me know if you need more info.

Cheers,
Erwin

That should be fix by r34864

Please let us know if you experience this problem in the next (pre)release.

I'm having the same issue with beta4.

Ervine, did the fix work for you ?
