Why is there no audio in my exported MPEG file?
If you burn an NTSC DV project to DVD using the MPEG audio format, audio is not exported (MPEG audio is not supported by the NTSC DVD specification). By default, the DVD export presets available in Adobe Premiere Pro for NTSC DV use the PCM audio format. It is recommended that you use the default presets when exporting an NTSC DV project to DVD.
You need to select “DVD” in your multiplex setting to get audio and video in a single file, otherwise you get two separate files. See "Multiplexer preset options" in the Premiere Pro 1.x Help for details. See "MPEG multiplexer preset options" in the Premiere Pro 2.0 Help for details.

Please also remember the benefits of separate video and audio files if one shall make a DVD.
1. The audio file is not good enough, do corrections and export only the audio and import that into the DVD authoring program (no need to wait for the mpeg 2 video export again).
2. Two (or more) versions of languages (or music) in one DVD.
Why is there no audio in my imported MPEG file?
If your MPEG file contains AC3 (Dolby Digital) audio then Mitch411 said:
If you've got Encore CS3 installed , copy the file ad2ac3dec.dll from the Encore CS3 directory and paste it into the PPro CS3 root directory. Once you restart CS3, you'll be able to import the file with the audio. This means if you've already have a project with the files imported, you'll need to remove the files from the project and then re-import them, or just start over with a new project.
Eddie, you're right. PPro doesn't import files with an AC3 extension, but it did import ac3 audio embedded in mpeg files from DVD camcorders. The ad2mcac3dec.dll that was included in 2.0 allowed those ac3 files to import as stereo (but not 5.1). It looks like that functionality was removed or broken in Premiere Pro CS3, but the functionality still exists in Encore CS3. You can copy the file over from Enc to PPro and get the functionality back. You may end up breaking something else, but it does work to allow the AC3 audio stream in the mpeg file to import.
Now aren't you glad that they decided to bundle Encore with Premiere Pro?

I've found several instances where Premiere did not favor my mpeg format and I got no sound though I thought it should be OK. I ended up running those files through MpegStreamclip (free download), outputing a ts file, renaming the file to .m2t, importing into Premiere, and everything worked fine. I've also found this great for fixing those little timecode problems that Premiere can't deal with.

Unplug your camcorder or change your playback preferences in Project > Project Settings > General > Playback Settings.

Also, if you Google mpeg +premiere +"no audio", you will get links to various forums that have workaround solutions.
Good luck, and enjoy your Tofurkey tomorrow...
