Cant connect phone to DVR

Ive called and chatted and called and chatted. Waited a week on a return call or email. My phone will not connect to my DVR so I can watch my recorded shows on the go. Ive deleted and reinstalled the app. It. Will. Not. Work. And nobody seems to know how to help me. Ridiculous customer service as well as ridiculous app.
