Other Choppy Blu ray playback

I'm using a Samsung Blu ray drive which came bunled with Powerdvd 9. The picture quality is fine, but the sound and picture jitter every 3-5 seconds.

I've tried everything, including different discs and nothing seems to help.

Anybody got any ideas?

Cheers

 

any way of benchmarking the drive to see if you are getting the full rated speed from it? does blu-ray use a different lens to DVD?

 

It works fine playing DVD's, it's just Blu ray discs that it doesn't seem to like. So could be related to the speed. I don't know what I could do to resolve it though.

 

try turning off sli, and see if that helps

 

are you using any kind of hardware acceleration with the graphics cards?

 

Just tried it again with SLI disabled and the same problem still exists so I guess we can rule that one out.

 

something running in the background?

 

I've closed all other programs and unecessary processes. The Nvidia control panel advanced image settings are all set to default, with no hardware acceleration that i'm aware of.

 

Hardware acceleration would be set within Powerdvd 9. what is your cpu usage like when playing Bluray?

Might be worth looking for a different blu ray player or updating codecs.

 

run the resource monitor to see if anything hidden is taking up required processing time

 

Does it still jitter if you switch to Windows 7 Basic theme?

 

powerdvd does that automatically

 

CPU usage tops out at 12%.

In the powerdvd settings menu, it won't let me uncheck the hardware acceleration box. Infact no options on the video settings menu are accessible.

 

Ahh, I've found that Nvidia's hardware acceleration for certain formats isn't always optimal, You've got plenty of spare CPU power that will be more than enough.

 

So what are you suggesting I adjust in the nvidia control panel?

 

As far as I'm aware there is no option in the Nvidia cpl for this but thinking about it if your CPU is using 12% then 12x4(cores)=48% on a single thread which would imply that hardware acceleration isn't in use.

I would suggest either updating your codecs, or if PowerDVD uses it's own codecs like VLC then updating to Powerdvd10 may help.

If updating the codecs doesn't help then I'd try using different media player that supports Blu-ray to see if powerdvd is the problem.

 

I might give that a go. However, I think I'll wait until Wednesday when i'll have my new processor and motherboard installed. Maybe that will make a difference. I'm looking forward to seeing what this 2600k can do.

 

Just to rule it out, have you tried playing at stock speeds/voltages?

 

Yeh I turned off afterburner and put my cpu back to stock, but still had the same problems. It's really frustrating because it has no problem with dvd's.

 

This might be useful.
