how to troubleshoot jerky video output

I have a LeadTek WinFast A 340T AGP Video card (nVidia GeForce FX5200) on a
system that I recently built. I just bought a Samsung 16x DVD ROM drive and
tried testing the video. I am seeing that the video output is slightly
jerky. It is clearly noticeable when watching flowing water - after every
3/4 seconds there is a fraction of a second pause before it continues again.
It is also noticeable when the camera is panning a scene, when a person is
running etc.

Can someone suggest how can I troubleshoot this? I un-installed all video
card related software (including the dirvers) and installed the latest
direct x from the micorsoft website. Then I re-installed the video card
software again. Then I installed power dvd.

I still see the same problem. Can it be related to the dvd rom drive? What
else should I check?

Here is my system info:
AMD Athlon 64 3200+ with the standard retail heatsink on socket 754
MSI K8N Neo FSR mainboard BIOS v1.4
Antec TruPower 380 W PSU and Antec Sonata case
Leadtek WinFast NVidia GeForce FX 5200 AGP Card
1 GB Patriot Ram
160GB SATA drive Western Digital
1 Samsung 16X TS-H352A DVD ROM Drive hooked on to IDE1
1 standard floppy drive
Windows XP


Thanks,

DMA is enabled on the MB and in windows?
VIA chipset? VIA drivers?
