suggestions welcome for playback rate problem

I am at my wits end in trying to figure out why with my new pc I can't get a solid 29.970 playback rate on a video clip with NO effects applied. I simply drag any clip onto the timeline and vegas just flickers right at 29.~. I cannot express the frustration that I have had over the past few days after trying to fix this problem by eliminating background processes and other tweaks. If anybody could offer any kind of solution or advice it would be greatly appreciated. Below is a decription of my processes and pc. I am using an external firewire hard drive for video. I have tried adjusting virtual memory to no avail and right now it's at 2048MB. Thanks for any help!

Have you tried playing the video from an internal drive? This would help rule out any external drive problem.

Virtual memory shoudn't come into play. It is primarily based on the CPU speed, data transfer speed and the video card.

What format and codec does the file use?

And do your project properties match those of the file? Ie, are they same framerate, resolution, PAR, etc? If not, you have to at least allow Vegas a little leeway since it's doing at least some work there. (To sync them up, go to File -> Properties, click the Match Media Settings icon (button that looks like a folder) and select your media file.)

I have tried the internal drive, still the same.

Format: AVI rendered in Vegas. And other captured video.

I tried the match media settings, still the same.

I do adjust properties in the "project properties box" and still the same.

Well, then something's screwy. I drop an AVI on a Vegas timeline with no effects applied, and it plays at the original framerate. And my machine (AMD Athlon 1.24GHz, 1GB RAM) isn't half what yours is. ;-)

What's your Dynamic RAM Preview (Options -> Preferences -> Video tab) set at? Putting it too high will take RAM away from Vegas' usual resources since it reserves it for special occassions (meaning, when you do a dynamic RAM preview).
