Compressing for a second time what was already compromised by the first compression.
Do you nest sequences (meaning putting a edit-sequence into another sequence), or did you use the exported mpeg2 from sequence 1 in sequence 2?
(I thought you described nested sequences, but Harm reads a lot so maybe he saw something I didn't :) )
It was a nested sequence.
I compressed the audio from the first sequence.
I did not compress the audio of the second sequence (although possibly there is an implicit compression in the MPEG audio encoding).
Try not compressing the first sequence, just nest it and then only compress the master sequence. It will save you one compression and possibly solve your issue.
Thank you -- I will try that. The reason I did it this way is that I wanted to export both a less-cut sequence and a more-cut sequence, so I did the less-cut first, including the audio effects I wanted, and then I used it as the source for the more-cut sequence.
I'm having another distortion problem although I haven't compressed nested subsequences.
My PP time line contains a sequence with approx. 40 nested sequences each containing DV clips. To encode, I frame serve using Avisynth and Quenc.
The resulting mpeg2 has a large number of clicks, pops and other brief
distortions. These distortions sometimes occur at points when the source has no sound (source is interview with predictable sound gaps).
The problem is reproducible - the distortion points are identical from
one encoding to the next.
Since Quenc is doing the encoding, I'm suspicious of it although it has encoded other, shorter sequences flawlessly.
Try using AME for the encode. See what happens.

Have you considered using HC Encoder instead? It does not handle audio at, so you'll have to export your audio from Premiere as a .WAV file or something, but HC is a much nicer video encoder.
Assuming that you're authoring in Encore, just output a .WAV file from Premiere and bring that into Encore. Encore will transcode the WAV file as needed when you burn to DVD.
I used AME to encode. There is good news and bad.
AME encoded a distortion-free mpg-2 But now PP crashes at start-up,
with or without a project. I just remembered why I was using
avisynth and QuEnc.
I've got a hefty, stable system (dual Quad core, 4gigs, up to date XP).
Here's the blow by blow:
The AME encode worked - no audio distortion.
I loaded the resulting mpg-2 into PP to check it and noticed extreme
video distortion - "heat wave" effect.
Then loaded it into Media Player which crashed.
Played it using Nero where it behaved fine until blue screen...
Rebooted, brought the mpg-2 into Encore. It worked, played clearly.
Tried to re-enter Premiere Pro. It now dies at start-up. Haven't seen
that in the last 9 months of usage.
When I get PP sorted out I am interested in HC Encoder.
Any suggestions concerning PP crashing at start-up. I realize, this
is off thread.

Now I'm back to the encoding problem. Am inclined to avoid AME.
Noticed that, although it's mpg-2 result was audio distortion-free,
it was nearly twice the size of QuEnc's mpg-2.
Will give HC Encode a try unless I find $6000 to spend on Avid.
HC Encoder worked very well. Thank you, Dan. Your postings have
helped me many other times.
