I'm trying to build an app which lets users choose videos from a list to create a XML playlist which would then loop. 

I want to have Roku read the playlist as a subcategory.xml file like this:

<feed>
<resultLength>3</resultLength>
<endIndex>3</endIndex>
<item sdImg="http://foo.com/images/custom.png" hdImg="http://foo.com/images/custom.png">
<title>Custom</title>
<contentId>10101</contentId>
<contentType>Talk</contentType>
<contentQuality>HD</contentQuality>
<streamFormat>mp4</streamFormat>
<media>
    <streamQuality>HD</streamQuality>
    <streamBitrate>2000</streamBitrate>
    <streamUrl>http://foo.com/content/foo1.mp4</streamUrl>
</media>
<synopsis>
A Custom Playlist
</synopsis>
<genres>custom</genres>
<runtime>572</runtime>
</item>
<item "a different playlist or another media item in the first playlist" ></item>
<item "a different playlist or another media item in the first playlist" ></item>
</feed>

Is it possible to add more <media> entries in the <item>? If I do that, it only plays the last <media> entry.

Or would I set something in a .brs file to read each <item> sequentially?

Thanks!
