Wow. I just found this forum for Xfinity DVR web/mobile app problems... this goes back years... It's not just me! Ugh.
So I have the exact same problem as everyone else. I had a DCT 3412i and went through 3 different tech support channels before the (nice) lady seemed to get frustrated and just said to bring my box in and exchange it for a newer one... that'll work, right?
Now I have the new box - a DCX3400 - and of course I still can't access the DVR Manager. Like the others said, the site says "syncing in progress" forever, and my mobile app doesn't even recognize a DVR in my house. Also can't change channels from the Android app or Xfinity's web listing: the latter says "No compatible cable boxes were found in your household," which isn't true, since I switched boxes to make sure it's compatible... And I have checked the "enable remote access" setup option, which gives me a code that I can't enter on the website because it's STILL SYNCING! The rest of everything "on the box" works just fine, including the DVR.
Backstory: I tried cutting cable recently (I had no DVR and am young enough that "appointment" television is useless to me) but they lured me back in with a good deal on a better package: featuring, importantly, a DVR.
But even with the upgrade deal, I'm considering just letting it all go. It sounds crazy, but I write for a consumer tech news site and so I know it's the little things that count - like all of the included features working as they're supposed to. It's just one feature and a web-cablebox connection issue, but it's stuff like this that drives me/people nuts about cable, and reminds me why internet entertainment services are quickly eating cable's lunch. It's a simple feature, it should simply work.
