DVR recording on the go, from your phone!

Why does COX say that you can record stuff on your DVR when you're not home?

I've downloaded the app, used the internet browser, etc, and it NEVER works. Not once. Ever.

My wife and I are at a restaurant and she's like "Ohh I want to record this!"

Well it's not the end of the world, but if you say that a feature works, then it should work. Yes, work closer to 100% of the time, not 0% of the time.

So, my problem, every time I get online and follow the steps to record, it tells me that a "problem has occurred, please try again later"

Is there something I am doing wrong? Can anybody help me with this issue? Thank you!!
