Rendering Problem with Mixed SD & HD

I mixed many many clips of HD (m2t) & SD(avi). After rendering for DVD (MPEG) the SD is fine, however much of the HD is fragmented. For example, rather than motion, it looks like a series of stills pictures that change every 5 seconds or so.

I've played with the settings and tried rendering just a 10 second mixed SD-HD portion (using looped regions) and I still have the same problem, however it's less pronounced (I get stuttering instead).

System Stats, laptop P4 3+GHZ, 512MB (system max), Two 320 G hard drives connected by firewire, 40 G harddrive onboard, 5400 RPM. (I've used this system for rendering many large projects so don't knock it). Vegas 7.0b, project output: mpeg-2.

What am I doing wrong? I know that next time I'll convert the video before I start the project, however now I'm stuck with many clips intermixed. Is there a way to pre-render the m2t clips so they don't bung up the final render?

The only time I've seen messy rate playback is mixing different rate clips on the timeline, ie. 24p with 60i. The result was jerky video in sections. You should use "Best" quality rendering. Are you sure it's not just a slow playback problem? Have you burned a test DVD and seen it on an actual TV from a set top DVD player?

I have not burned it to DVD, but I'm certain that it did not render properly. I will retry rendering tonight to AVI and see if I am having the same problem.

I did not use 24p and the SD was shot on my VX2100 using 16:9 ratio.

I've done that numerous times and it is just fine. Are you going to DVD?

Yes, going to DVD. Why?

It turns out that the problem was delays in the playback. After burning it to DVD, it worked just great on the same computer.

Thanks for the suggestion. Is there a better viewer than Windows Media Viewer to view mpeg files?

WMV should work fine. Sounds like contention somewhere, resources fighting. Are you playing off of one of the firewire drives? Maybe there are some IRQs sharing other resources. 512 RAM is fine unless you are using some other programs/anti virus while playing back.
