DVR and Recordings

I am trying to access my DVR using the iphone app and a web browser.  When I log to Saved Recordings it is empty.  I now that there are recordings on the DVR.  I am also not given the option to record a show when viewing the live guide.  Shouldn't this be an option?  The Comcast rep told me that I need to have Comcast interet and the X1 box.  for this option to work.  I have a Motorolla HD dual tuner DVR.  Thank you in advance for any help.
