Warning Response - 3 tier severity levels. 1 being the most critical.

Frame - a video frame response from the WonderBox

 <frame>

 		<compression type="uncompressed|jpeg|huffyuv" />	 
		<size width="640" height="480">
		<origin x="0" y="0"> <!-- We can set a region of interest in the frame request -->
		<channels>3</channels><!-- We do support IR... in the future -->
	</meta>

	<device>0</device><!-- essentially the video port -->

	<!-- this is retiming info, for playback - especially during seek, where we could return faster than capture does -->
	<timing>
		<captureTime>yyyymmddhhmmsszzz</delta>	<!-- year, month, day, hour, minute, second, millseconds of capture time -->
	</timing>

	<!-- on second thought, this id can be made into a simple integer representing the frame
		offset since the server began recording on this channel.  This would allow
		for unique identification of roughly 30,000 hours of video. We're safe with this.
		Of course, when you seek, you need to specify the channel and type.  

		Also, since we support this type of definition, we dont need to worry
		about telling the user how many frames are available.
