 When a new recording starts or a recording finishes (?), the PBB is asking
 for the previews even when it's not visible due to playback of video.
 Often when this happens, it seems to affect the playback, causing
 noticible halts.

 Additionally, some of the HandlePreviewEvent calls (as above) seem to be
 missing an argument (the code wants >= 5, there are 4 reported).  Not sure
 if these two things are related.
