detect that a video has played / and will loop?

I'm wishing for an event that would tell me that a video is about to loop (really, that the video is done playing).

Any way to be notified that a video is done, short of manually setting a timer and having that fire off in a given number of seconds? (and I imagine that breaks real quickly if the user hits the pause button)

And yes, I thought of appending PARCEL_MEDIA_COMMAND_UNLOAD to the command list that plays the video - no go...

Not that I know of. I think you'd have to know the length of the stream beforehand (possibly retrieved via an HTTP query if there is some web service that will give that to you) and use a timer from the moment you start playback.
