I just upgraded to PD19 from PD14. I am happy that the Preview function is a lot more stable and I don't have to constantly invoke Task Manager to kill PDR (knock on wood). However, the video and music under Preview still is out of sync (quite seriously sometimes - the music has finished playing and the video is still back at the beginning!). It makes it very difficult to work on a project that is music sensitive. I often have to Produce a mp4 and hand time it to resync the two. It's very painful. Is there a way to work around this?
