Display Problem

[AWS]

Win 7
CoreAVC 3.0.1
Nvidia. Current as of this post date
Sage. Current as of this post date.

Occasionally when playing back an MKV file, when there is a large change of scene, the image will freeze and the next scene will move the previous screen pixels till eventually the new scene bleeds entirely through.

I'm thinking its a codec issue not a graphics card driver. ?

Ideas?

What nVidia graphics care are you using? almost sounds like a memory issue...which, of course, could be due to the codec not making best use of the hardware.

Hi.
The card is an nvidia 8600 GTS with display driver 280.26.

It's a fresh build on W7x64SP1.

I have been using the card since the 8600 GTS model was new. Yeah, it's old but has never had an issue hence it's in operation still today.

I'm leaning towards a codec problem. I'm using CoreAVC 3.0.1. Plays AVI (XVID codec) fine, and any SD material ok. When I playback hidef material in the MKV container is when the glitching occurs.

Ideas?
Thanks

I've up'd the size of the Java heap size (wording?) to 512(dec) and the same problem is there. I have 6GB of physical RAM in that machine. 512MB seemed like a good place to start.

Another idea I have is that maybe my disk I/O requirement is greater then the disk I/O throughput. After moving to this different hardware (different mobo) I no longer had the same on-board array capabilities. Yet in order to make use of every single GB available to me on my media library (HDDs) I tried using the Windows "Extend volume" (it's a Windows Dynamic Volume spanned across two different sized disks). Every bit of my being and years of experience screamed against this configuration for a media "drive" setup but I proceeded anyway out of curiosity and, somewhat, need. I don't have or know what the overhead requirements are for this MS "RAID" setup. Any one have any ideas?

So I guess a simple test of this would be to either temporarily install another HDD, copy a MKV to it and see if the image freeze and bleed occurs. Or maybe on a thumb drive. Try that tonight.

Playing a MKV file off a thumb drive and off of a new HDD (single) made no difference.

So it doesn't seem to be throughput. The only thing left is the graphics card. the 8600 is an older card w/only 256MB of ram. I know my old ATI 2600 wouldn't play HD movies recorded from our HD Camcorder (I don't have a BD player so I can't rip movies or play them).

now that i upgraded to an AMD A6 processor (and even before with a silent ATI 6570) the HD movies played fine. But if you have seen my current problem, there seems to be some weird artifacts on the screen. I think it might be driver issues.

Anyway, maybe a friend can lend you a newer card with more/faster on board ram and see if that solves the problem. I'd recommend an AMD card but I think there may be some issue with Sage not playing nice with AMD.

I found that when I change the codec from CoreAVC to the built-in Windows 7 codec, the issue resolves itself. I've contacted CoreAVC and they are assisting.
