"Unpausable" media - control bar undocumented feature

Question

As I was looking for a way to disable play on some video ad, I stumbled upon a hiden feature of the control bar:
- The play and pause buttons toggle their visibility (and presence in layout) when metadata with the key "Advertisement" is not null on the media.
The feature is not fully functional though. Line 64 of "PlayButton.as" needs to be modified:
//visible ||= media.metadata.getValue("Advertisement") != null;
visible &&= media.metadata.getValue("Advertisement") == null;
Then, you can do something like this:
var metadata:Metadata = new Metadata();
media.metadata.addValue("Advertisement", metadata);
... and the play/pause buttons won't be present while your media is in the player.
Note: I figure this is the most "kosher" way of dealing with the problem. Modifying the PlayTrait (extending it) would actually make it more awkward to handle the media. This method only limits the end user by modifying the GUI. You can still play/pause internally without having to work around your own alterations, and you're less likely to make the media player complain.

Does NeedleDrop v3.0 do the trick for you? This is the information given for the script:
This applet plays each track in the selected iTunes playlist for a chosen time interval starting at a chosen number of seconds into each track, beginning with the selected track (if no track is selected then playing will start from the beginning of the selected playlist). Handy for quickly perusing a playlist.

(Thinking here that if you put the Track in question into its own playlist, then you could use the NeedleDrop functions to zoom in on a particular segment of the track.)
If it isn't quite what you're looking for, there might be something else at Doug's AppleScripts:
