mrss_grid_template.1.0.1 multi playback issue MP4 and HLS

I am doing some testing on the mrss_grid_template.1.0.1 and I would like to be able to play either MP4 or HLS Video. So far I have only gotten it to do one or the other by changing the code in the NWM_MRSS.brs

	xml = CreateObject("roXMLElement")
	if xml.Parse(raw)
		for each item in xml.channel.item
			newItem = {
			  guid:             ValidStr(item.guid.GetText())
				streams:			    []
				streamFormat:	    "mp4"
				minBandwidth:     250
				'maxBandwidth:     2200
				actors:				    []
				categories:		    []
				contentType:	    "episode"
				bookmarkPosition: 0
			}

			' title
			tmp = item.GetNamedElements("media:title")
			if tmp.Count() > 0
				newItem.title = util.HTMLEntityDecode(ValidStr(tmp[0].GetText()))
				newItem.shortDescriptionLine1 = util.HTMLEntityDecode(ValidStr(tmp[0].GetText()))
			else
				newItem.title = util.HTMLEntityDecode(ValidStr(item.title.GetText()))
				newItem.shortDescriptionLine1 = util.HTMLEntityDecode(ValidStr(item.title.GetText()))
			end if

if I change "streamFormat: "mp4" to streamFormat: "hls" then it does play hls fine but it disables MP4 playback. All attempts have failed to get it to play both, How would I allow the HLS playback without disabling the MP4 playback?

Any advice would be greatly appreciated.
