I ran a 720 x 480 DV file through the Dione models and they sped up the audio and raised its pitch.
The video appeared to be the correct speed and frame rate.

The pitch being raised is probably directly from the audio being sped up.
One solution I can offer is to use ffmpeg (which is free) to extract and create a separate audio file, and then re-compile the audio into the upscaled video.
It adds a couple more steps to your workflow, but it doesn’t take long (a few seconds to extract, and a few minutes to re-compile).
I know some ways of putting the original audio back into the video, but I wanted to make sure Topaz knew about it.
Interestingly, it seems the audio speed has only increased by 25% rather than doubling.
