Jittery Blu-Ray playback

I've watched three blu-ray movies on my PC so far and whilst watching all three, on random occasions, I have experienced jittery playback. It really bugs me and I'm desperate to find out the culprit in terms of the hardware that I use :( I'm guessing it's between the processor, graphics card, or the blu-ray drive itself.

My processor is a E6600 2.4GHZ, graphics card is BFG 640MB 8800 GTS, and the blu-ray drive is the Pioneer BDC-202BK. The graphics card is hooked up to a Samsung 32" Full HD TV (1920x1080 resolution) via DVI to HDMI adaptor and HDMI cable.

Does anyone have any suggestions as to how I narrow it down or have a good idea what the problem is likely to be?

Thanks.
 
What's your CPU sue during playback and what software are you using? Your system probably isn't fast enough, specs are borderline, but a bit of overclocking would fix it.
 
I have 30 processes running at the moment. I've recently had a sort through and stopped a number of them that were set to run at startup. I've also removed AVG 8 from the system too so at the moment I don't have any AV software running. I have Zonealarm running though, but doesn't seem to make a difference if I have it running or not.
 
ok i've tried disabling the acceleration in powerdvd, but the tick box is shaded in grey so i've been unable to turn it off. I did however look on my nvidia control panel and theres a setting called multi display/mixed-gpu acceleration or something like that. The option selected was multi display, but i've now changed it to single. Do reckon thats done it?

Silly me :rolleyes: Just unticked the hardware acceleration box in powerdvd whilst there was nothing playing. Just tried another blu-ray disc and it jutters even more without the acceleration. I'm guessing this is trying to tell me something about my card?
 
DXVA (the offloading off decoding to the GPU) is often flaky at best so I wondered if that was the issue. Unfortunately without it your CPU isn't fast enough for decoding on its own.
I would update your graphics drivers and also try out another program such as Arcsoft.
 
Ok i've checked out my driver and it's the current one out for my card (175.19). I downloaded a Cyberlink program, which checks your system for blu-ray compatibility. It terms of basic playback my system passed with flying colours, but on the advanced section it has a few let downs. Would this be of any significance you think? I've just downloaded a trial of the Arcsoft program TotalMediaTheater, but will try it out later during my lunch break.

His card does do hardware accel for Blu-ray.

Those hardware dual-video decoding checks are for the advance blu-ray features. This is taken from the cyberlink web site.
'Advanced features are defined by the BD specifications Profile 1.1 and 2.0. Picture-in-Picture content can include two high-definition video streams or one high-definition and one standard-definition stream. BD Advisor tests if your system can support Picture-in-Picture content by testing for Dual DxVA support as well as network connectivity'

I wonder if he has some other codecs installed that are conflicting?

Also, I would try forcing the player software to high priority and/or run on one core. I have resolved video stutters this way before.

I've had a look at my program list and found the following codecs:

Combined Community Codec Pack
DivX Codec
GPL MPEG-1/2 DirectShow Decoder Filter (codec?)
K-Lite Codec Pack 3.01 Full
oggcodecs 0.71.0946

Do you think it's likely that one of these if not some of these are conflicting?

Monitor set to 24hz?

The only two options i'm given for the refresh rate of the TV are 50hz and 60hz.

I'll try and set the player to highest priority and see if that makes a difference.
 
I installed it about a year ago and because I wanted to be able to watch many different types of video file without having to download an individual codec for each one. Does this codec pack have a history of causing trouble and conflicts?
