Thank you for reaching out to our online forum. I'm not exactly sure what DRA is but I'm guessing that you are talking about Dish Remote Access. If this is correct it will only work with the sling adaptor or the Slingloaded Dish boxes. If you have one of these units you would have to contact Dish Network to get those units up and running. We do not do any of the trouble shooting on these units. If you are trying to use "DRA" with one of our Slingboxes (Solo,Rro-HD,350,500) you would have to get our app. I will post a link below that will show you what devices are supported by the Slingplayer.
I hope this helps,
Sling Moderation Team
