Playing high resolution video

[rjc7394]

When I play WMV high resolution video (1920x1080) from DVD drive in WMP and move the video forward the video takes 6-12 seconds to continue playing. I'm not sure which part of my system holds the video up: the DVD drive, RAM, etc. I don't have hesitation when I play 1280x720 WMV.
What type of system do you need to play high res video with no interuption?
I have Gigabyte M57 SATA mobo w/2000 MHz FSB, CPU 2.5 MHz Athlon, 4 GB RAM, Gigabyte 8600GT graphics card, Pioneer DVR-215D burner (16x read speed). All new equipment.

I'm not sure what the video is dependent on but you should try updating the drivers for the video card if you hadn't done so already.

I had a similar problem where I experienced lag while watching videos and updating the drivers helped.

Sounds like the DVD drive is not fast enough to read the data and is having to buffer. Easy way to tell if it is RAM or CPU is to open Task Manager, tell it to always stay on top, and watch the CPU and RAM usage when you skip forward in the movie. If the CPU hits 100% or RAM is near zero free, that should be the problem.
