HLS + MP4 in XML

I'm trying to add an HLS stream to my XML which is all mp4.

This works great for the mp4:

<item sdImg="http://discolemonade.com/roku/images/thumbs/OOF/OOF_december2014.jpg" hdImg="http://discolemonade.com/roku/images/thumbs/OOF/OOF_december2014.jpg">
		<title>12/28/14</title>
		<contentId>70003</contentId>
		<contentType>Music</contentType>
		<contentQuality>SD</contentQuality>
		<media>
			<streamFormat>mp4</streamFormat>
			<streamQuality>SD</streamQuality>
			<streamBitrate>1500</streamBitrate>
			<streamUrl>http://www.archive.org/download/OOFTVPresents120714YouTubeFastStart10000Kbps/OOFTVPresents-120714-YouTube%20Fast%20Start%20%2010%2C000%20kbps.mp4</streamUrl>
		</media>
		<synopsis>Part Time, Shannon and the Clams, Guantanamo Baywatch and more!</synopsis>
		<genres>Music</genres>
		<runtime>1834</runtime>
	</item>	
	

But changing the values won't load the HLS stream.

<item sdImg="http://discolemonade.com/roku/images/thumbs/OOF/OOF_102214.jpg" hdImg="http://discolemonade.com/roku/images/thumbs/OOF/OOF_102214.jpg">
		<title>OOFTV 24/7</title>
		<contentId>70004</contentId>
		<contentType>Music</contentType>
		<contentQuality>SD</contentQuality>
		<media>
			<streamFormat>hls</streamFormat>
			<streamQuality>SD</streamQuality>
			<streamBitrate>596</streamBitrate>
			<live>true</live>
			<streamUrl>http://pablogott.videocdn.scaleengine.net/pablogott-iphone/play/ooftv1/playlist.m3u8</streamUrl>
		</media>
		<synopsis>Music videos, minidocs, and more! The music TV you always wanted.</synopsis>
		<genres>Music</genres>
		<runtime>100</runtime>
	</item>

Also, since this is a 24/7 stream, is there a better way to represent that in runtime?
