DVR Manager: We are unable to detect a compatible DVR in your household.

Hey folks, 

I upgrade to X1, however, I cannot schedule my new DVR online: http://xfinitytv.comcast.net/mytv/dvr

I get the following error:

DVR Manager is available in your area. However, we are unable to detect a compatible DVR in your household.

Can anyone assist me?  Is there some sort of entitlement or permissions missing on my account?  

Thanks!
