I'm using Win2k with a velocity 100 and the DivX 3.11 Codec, it skips every few seconds a little bit forward. Anyone had similiar problems, and can anyone ffer any help. I'm using a dual celery 550, it has no problems anywhere else and I've tried the DivX with them underclocked, same problem.
Jumpy DivX -> can anyone help?

Have you tried just one divx or multiple ones?
I had a divx movie once that would skip around a would stop due to bad sectors, anyways what i'm saying is that it could be that one divx that's messed up. But if you have tried multiple ones then I am stumped.

Hmmm, my guess is that you have an SB LIVE! as well. I had exactly the same problem on my BP6 with dual celeries 366@550. My guess it's the Creative drivers for the LIVE on a dualmachine. You can make it go away by running DX-diag and put the hardware acceleration in the soundtab two or three notches down. I know it's not too elegant and a PITA, but that's the only solution I found for this particular problem.

Why don't you turn down Hardware acceleration in WindowMediaPlayer and see if that helps. And SuzieQ I swear I have seen you somewhere. Which other boards do you frequent?
I had that problem but only when I right clicked on movie, went to Properties, then to Codec or something like that, then to MPEG4/DIVX and there was a quality slider. If I put the slider past 2 or 3 it would would do that but otherwise was fine.
Been watching and encoding DivX flickz on my SB Live!-equipped computer for about 5 months now, no problems here...
well it all depends on the quality settings you set for decode. a celly550 cant pull off max settings.
I have that problem too, but I'm not sure if it's the encoding or my computer. But.. I do have a 1ghz so I don't think processing power is an issue. I'm running Win2k.
As others have mentioned, adjusting the CPU (Quality) slider in Windows Media Player's properties will improve playback smoothness at the expense of visual sharpness. From my experience and things I've read, you would indeed need a GHz or better machine to take advantage of the 4 & 5 quality settings.
However, the original settings used to encode the film also factor in, particularly with high motion action scenes. If the problem is with movies you've encoded yourself, try adjusting the Crispness slider to around 70 (default 100) when selecting the DivX codec properties. I've never seen a good technical explanation for what the crispness setting actually modifies although it seems reasonably intuitive. Presumably if the crispness were set extremely low, quality would progressively suffer. However, I cannot discern any difference in the quality of still scenes between a value of 70 and 100, it merely improves the smoothness of fast-action and camera pan scenes. So I now use 70-75 for all of my movies.

Well, it looks like my regular DVDs play back very poorly, too.
[edit:] Just dropped my color depth down to 16bit from 32bit. Are you running at 32bit color? If so, try dropping it. It got rid of my DVD & DivX skpping!

I have a simmilar problem, I have loads of Divx Movies, movies that I´v divxed myself and movies that I´v downloaded from the net.
The problem is that about 50% of them play extremely poorly in fullscreen mode, and some just fine.
I have a G400 and Athlon 750

Hmmm, some people seem to have some reading disabilities.
It's the combination of Dual CPUs, W2K and the SB LIVE!(maybe other soundcards too).
There's nothing wrong with the LIVE if you have it running DiVX on a single CPU-system with Win2K.
When home users start to build Dual CPU-systems there were quite some incompatibility problems with them concerning soundcard-drivers. And at some points I guess there still are. For example running DiVX movies in Win2K on a DUAL machine.
The problem is, the sound seems to go to slow(not noticable) and goes out of sync with the movie and after a couple of seconds it seems like the movie is trying to play catch-up with the sound and moving really fast for a second. At that point sync is back, but the problem persists, happening every ten seconds or so.
And the CPU(quality) slider in Media-player won't do anything about this particular problem, believe me I've tried.
For people thinking they know me, that's possible. I used to frequent the AGN BBS quite some time ago.

i dont think DUAL cpu helps DivX decoding
C550 does it at an acceptable speed just that there are some very complex scene where it will start dropping frames

Is everyone running 32bit color or 16bit color?
If the former, definitely try it at 16bit. I'm sure a Celeron 550, especially duals, can handle any DivX or DVD decoding.

32/16bit has NO effect on decode speed as the video is overlayed on to your screen. it will look the same regardless of 32bit/16bit color
C550 does not have the full power to decode DivX, but can handle it smoothly in general

xtreme2k:
I beg to differ. Consider this:
I have a P3-1000mhz running in Windows 2000 with 384mb of RAM. I run a fully SCSI subsystem with the exception of my DVD-ROM drive, which is an IDE Pioneer. I run a Matrox G400 Max with the latest drivers, and I run my screen normally at 1600x1200 @ 32bit color. All DiVX movies are played back from the U2W SCSI drives, all DVDs are played back from the IDE Pioneer.
For DiVX movies I simply use the codec and Windows Media Player. I left all the settings at default (high quality at a speed sacrifice) For DVD movies I use both WinDVD2000 and PowerDVD 2.55
Now, set at 1600x1200 @ 32bit color, when I play back DVD movies, it skips frames every so often during scenes with fast movement. The same occurs with DiVX movies.
I reduced the color depth to 16bit, and at the same resolution, not one movie skips anymore, DiVX or DVD. Other than the color depth change, I did not modify any other setting or tweak any system performance properties. What can possibly explain the drastic performance change other than color depth?
I think with overlay, the decoding needs to be applied on top of my current display - that is, whatever the DVD's resolution is - 1600x1200 - and its color depth - 16bit, or whatever DVDs are usually played back at - on top of 1600x1200 @ 32bit. I think that's where the problem is. Not so much that decoding that is affected, but the fact that it has to put a high quality decode on top of an already high quality desktop screen.
[edit:] I just tried out the DiVX movies that I had on my roommate's Celeron 550, running Windows 98, 128mb of RAM, and the original TNT, and there are _no_ problems at all. A Celeron 550 is sufficient to decode DiVX movies. However, I would like to also point out that setting his color depth at 32bit didn't make a big difference, but that could be associated to his much lower 1024x768 resolution.

it seems like your video card does not have Video Acceleration at 1600x1200 at 32bit color
that makes the difference why your comp is so skippy
i remember having a S3 Trio64V+ 2MB and it was one of the first card to ahve Video Overlay Acceleration
i tried running in 8,16,32bit color desktop - the MPEG video looks the same regardless (this shows they disregard desktop color depth on overlay modes)
HOWEVER, at 32bit settings, video cannot be overlayed on a 800x600 screen. (RAM/core limitation) (acceleration disabled - choppy as hell)
however at 16bit video can be overlayed up to 1024x768
what i am getting at is the video overlay capabiality of your card
maybe it just cannot do 1600x1200 at 32bit overlay
that is what makes the difference
NOT THAT the decode process is anymore complicated at 32bit

i just tried playing DivX on my 868E/124 with G2/GTS
found absolutely no difference between 1600/32bit vs 1600/16bit
same speed
same picture quality

yup, video card power my geforce supports 1600x1200@32bit with overlay, nice and smooth. my older cards did not. just lower the resolution and the color depth until it is smooth. If that works, its your video card.

Anyone who seriously thinks you need a Ghz to run DivX is frankly off their trolley. I tried changing color depth, no change, I tried changing playback quality, no change. I guess I'll just have to bin one of my processors, never mind. Alternatively I could wait for new SBLive drivers.
All in all not a perfect solution, but I appreciate the help, cheers.
