Roku signup vs Online signup

I signed up for DTV Stream on my Roku device. I also hoped to add the Movie Extra Pack. I've found out that it's not possible to do that if you've signed up with your Roku, so I've elected not to renew via Roku. I've tried to go online to remedy the situation and it won't allow me to sign up without getting their Gemini set top box. That adds another $15 Gemini fee to their advertised monthly subscription and a possible additional Regional Sports fees. I've been in contact with the DTV president's office and got absolutely no satisfaction. Any suggestion from anyone? My Roku subscription runs out in two weeks.
