Question reguarding multi-cores.

[w00b]

Hi, I just installed a few things on pretty much a fresh install of windows XP 32 bit. I have media player classic, xvid codec, and ac3 filter installed. When i go to play movies i notice many 'splices' thru-out the video.. I can only guess that this is because of my multiple cores. After searching thru the XVID options, i noticed that the Deblock and Dering options seem to get rid of this problem, but I'm wondering if this is the correct solution to this problem. My specs are as follows:

Intel Quad Core Q6600 2.4GHz overclocked to 2.8GHz
2GB of DDR2-800, actually clocking around 920MHz
eVGA GeForce 8800 GTS 640MB
2x 174GB Raptor HD in RAID0 configuration
Windows XP Professional 32 Bit

Can you post a screenshot of the artifacts? That'd help determining where they come from and what to do.

a screenshot.. if i can figure out how to take a screenshot without it showing the video as black i guess.. not exactly sure how to do that.. the best way i can describe it is like a 'tearing'.. it's not strictly in one direction it's like a splicing when there is a lot of movement. like if someone was walking from left to right it might show one part of their head slightly infront of the rest of the body, just for a split second, and then it will be normal for a second, but if there is still movement it will 'tear' again. i don't know if this is making sense so i will try to post that screenshot :)

ok yeah i seriously can't figure out how to take a screenshot of the overlay.. if someone could tell me how to do that i could probably get a screenshot of this.

it also occurs when someone turns their head, you see the 'tearing' effect. this only happens when i don't have deblock / dering on in the xvid options, i'm using the latest xvid 1.1.3 and media player classic. all other options are set to default and untouched.

You have to switch back to old renderer or VMR9 to get a screenshot, or use a tool like fraps that can access the overlay. Alternately, you can just trim some of the file out in virtualdub.

Hmm, if it's not tearing causing that effect, then it's a mystery... perhaps it's decoding with the wrong IDCT, since there are several different common ones. Usually it tends to look like streaks or weird textures getting left behind after an object moves by, though.
