Nested projects and audio

Anyone have a problem with making a longer nested project match separately rendered audio without drifting out of sync? I have a film divided into 8 projects. I rendered each project to 8 respective .avi files, lined them up end to end, then laid down audio tracks (not in-camera, separately recorded from the boom mike), FX, music, and mixed them into one 92-minute audio track.

Problem is, if I drag the 8 .veg files to the timeline and try to use them in lieu of the 8 .avi files, after 15 minutes or so, the picture in the .veg files has 'fallen behind' the audio track. By the end of the 92 minutes the audio is 2-3 full seconds ahead of the picture. I wish I could figure out the problem because I'd rather render straight from the nested projects to one long MPEG-2 file, hopefully for slightly better picture quality.

The alternative--I think--is to render 8 separate MPEG-2 files and join them end to end, perhaps with a Satish product?

This probably isn't a fix, but can you render out 8 sections of audio and import them as nested veg files to see if that way makes a difference? Might be worth a look.

Also, have you tried a dynamic ram preview of one spot where it is out of sync? It may not be, it just might be that the preview is out of sync. So, it might be a false alarm.

Edit: Part of the text I originally typed dissappeared from my post? What the...? Anyways, I have added it back.

Why render as mpeg-2, that's a lossy codec.
Render to 8 avi files and then join them together in the one project.
That's how I was doing 'nested' projects before there was nested projects and why I've never found the new feature all that exciting.

Well I am already doing the 8 avi file end-to-end method. That works OK. Just being aware of Spot advising going straight to MPEG-2 when there's a lot of corrections and/or FX, as I recall.
