As far as I can tell, all it requires is a simple edit of the pose file.

Open the .pz2 in a text editor. Near the beginning of the file you'll see a section labeled "movieInfo".

Example:

{<br></br><br></br>version<br></br>      {<br></br>   number 3.0<br></br>  }<br></br><br></br>clearFigureKeys 134<br></br><br></br>movieInfo<br></br>       {<br></br>   numFrames 134<br></br>       framesPerSec 30<br></br>     soundFile C:Temp3Sabrinaconnery1.wav<br></br>                 0 0<br></br>        }<br></br>actor head:1<br></br>   {<br></br>   channels<br></br>            {<br></br>           targetGeom OpenLips<br></br>                 {<br></br>                   keys<br></br>                                {<br></br>                           k 0 0.000000<br></br>                                sl 1<br></br>                                lin<br></br>

Delete the entire movieInfo section, brackets and all, and save the edited file to the Library folder.

Example:

{<br></br><br></br>version<br></br>    {<br></br>   number 3.0<br></br>  }<br></br><br></br>clearFigureKeys 134<br></br><br></br>actor head:1<br></br>    {<br></br>   channels<br></br>            {<br></br>           targetGeom OpenLips<br></br>                 {<br></br>                   keys<br></br>                                {<br></br>                           k 0 0.000000<br></br>                                sl 1<br></br>                                lin<br></br>                         sm<br></br>

Now you can apply the pose file anywhere in the timeline. You'll need to splice the audio files together and import them into Poser manually.
