what type of MPEG2?
I encode MPEG2 TS files regularly and haven't noticed the issue.
However, I typically do it straight from Premiere with the "export" instead of "queue" option. Have to tried doing it that way & do you still get the same issue? I usually "use previews" as well, if that might make any difference.
Tried your suggestion as amn MPEG TS straight from PPRO but no difference.
I am mux'ing as MPEG.
I'm now using a work around of AC3 (Dolby) rather than MPEG audio, which seems just fine.
(My workflow includes exporting at high bitrate intermediate file (100Mbps) before encoding for Bluray and DVD outside of adobe.)
Thanks for responding

In that case, you should probably be using separate .wav files for audio, not MPEG. And use a lossless DI format, like Uncompressed, Lagarith or UT codecs, for the video. Don't create a muxed file for DVD or Blu-ray compression.
I can't offer you an answer but I did run into a similar issue recently with a project that was shot at 23.976 frames a second and exported at 24 frames a second. After I noticed the audio sync issue I exported it again twice at 24 and at 23.976. For both exports the audio was fine. Like I said I can't offer you a straight answer, but maybe exporting again might fix it. Good luck.
