If I do not want to have a separate SD stream, only an HD stream for my published channel how do I display a screen when SDTV mode is detected that informs the user the channel is only compatible with HDTVs?

I know that I can get the mode the device is in by using the roDeviceInfo component, specifically the GetDisplayType() method but what should I do next to make this message appear for SDTV users?

Just use roDeviceInfo to check if the device is in HDTV or not, if not, then set your video playback parameters to indicate SDTV mode, and the device will auto - downscale the HDTV stream to display it in SDTV mode.

Is this added into the XML file?

For example, one of the items in the xml file is:

<item sdImg="http://relevantfl.org/roku/artwork/RCFL_MIM.png" hdImg="http://relevantfl.org/roku/artwork/RCFL_MIM.png">
<title>Miracles In Motion, Ep 13</title>
<contentId>10020</contentId>
<contentType>Religious</contentType>
<contentQuality>HD</contentQuality>
<streamFormat>mp4</streamFormat>
<media>
<streamQuality>HD</streamQuality>
<streamBitrate>1500</streamBitrate>
<streamUrl>http://relevantfl.org/roku/miraclesinmotion/Miracles%20In%20Motion%20with%20Pastor%20Chris%20Sarno%20Ep%2013.mp4</streamUrl>
</media>
<synopsis>Miracles in Motion episode 13 with Pastor Chris and Liz Sarno</synopsis>
<genres>Religious</genres>
<runtime>1710.6</runtime>
</item>

Should I add the item again with a contentQuality and streamQuality of SD with a streamBitrate of 500? or is the Bitrate held at 1500 and the contentQuality and streamQuality the only things changed to SD?

If you remove the "streamQuality" tag completely, it should work in both SD and HD. Specifying a streamQuality of HD will prevent it from playing at SD resolutions.
