Preset without Playlist...Videos Don't Load

First off: this is just an amazing module. Clearly the future of video for Drupal.

I've got an odd problem...more so since it hasn't been mentioned previously in an Issue that I can see. When I create a preset with the playlist disabled, videos won't load...I just get the endless "loading" loop. Reactivate the playlist in the preset, and everything is fine. This is true whether the player is accessing one video or several. Seems to be the case no matter which theme I use. Is there something basic in setup that I'm missing or is this a bug? I've got the latest version installed in a 6.19 site.
