Choppy video

Guest

My video has been working great till the other day. I tried to play an .avi from my D drive and it stuttered real bad. Playing .avi off my C drive, however, worked fine. I checked the performance chart while each was running and found something weird- when video was playing from my C drive (good video) only 40-55% of CPU was being used. When playing from the D drive, the CPU was peaking at 100% usage. I think this tells me something but I don't know what. Yes- I defragged & ran scan disk, but didn't help. I ran a diagnostic program on the D drive (Maxtor), and it passed. Help!

Maybe the C drive is a faster 7200 rpm model, while the D drive is an older
model. Maybe D drive isn't configured for DMA operation. Do you have a
program that checks hard drive speed?

Are you using a compressed drive on D:? That will really slow things
down....

If that isn't the case, you might try opening your Windows Task Manager and
stopping all unnecessary tasks. You could drop them out one at a time, and
write them down as you eliminate them. If you find one that eliminates the
problem you can identify the file, and then decide if you should prevent it
from running. I doubt if it is a DirectX problem. Perhaps your computer is
indexing or running some other function that is competing for CPU time.

Did you add new video editing software or a Dazzle adapter? The Ligos MPEG
Decoder that comes with Dazzle is slow. If the problem is real recent try
restoring your computer to a time when it was working properly. You might
delete and reinstall your DVD software. WinDVD (or what ever was supplied by
the manufacturer of your computer) contains the MPEG Decoder that your
computer should be using.

Both drives are 7200 & DMA. Both drives have made perfect video in the
past. This is a recent problem. I ran diagnostics on the D drive and it
passed the test. This seems like a registry problem or DirectX. Running
dxdiag turned out fine.
