After seeking forwards a couple of minutes from the start of the recording we then try to jump back to the start.

	Looks ok up to this point. Video and audio timecodes are similar.

	But then an audio decoding error occurs...

	...and the audio timecodes jump backwards to much lower values than the video timecodes. This is followed by a bunch of these...

	...which seems to show audio trying to catch up to video.

	But later we get this. Note that audio timecodes have not incremented enough to reach video timecodes. Note the massive audio delay (137+ seconds!).

	...? It seems like video has now fallen behind the audio. Odd. How did the timing for the audio and video pass each other without meeting?

	A bit later on it looks like things have finally synced up.
