This is a great question! Below I have provided a link that will help explain the differences between Dish Remote Access and the Slingbox Solo.
If you have any further questions, we are more than happy to help!

Fair response but it didn't address the original issue, which I am now experiencing as well. For some time one could add a Slingbox Solo as the Sling Device associated with a Dish Receiver in the DISH Remote Access Account settings. When the user wanted to add a Slingbox to the Dish Account the Dish webpage requested a Slingbox login and the user would specify which Slingbox was associated with each Dish receiver. Now selecting "Connect a Sling Adaptor" in the configuration page redirects to an advertisment for the Dish Sling Adapter.
My Slingbox Solo worked great with both the DISH-online viewer and the DISH Remote Access Mobile apps for a couple years, now it won't work without purchasing a couple more full price mobile apps since I can't transfer the license from my Windows Pocket PC!
Is there some way to put this capability in place again?
