DVR Network Unavailable - Error 2.1.2.1

What DVR do you have? As in what model and software does it run? The model number will usually be on the front, and the software is the screen that flashes on the TV when the box reboots or resets.

Sounds like a signal problem. Even though you only have 1 DVR, the whole home type DVRs  (Cisco type) still need to connect and talk to Cox for the guide data and DVR schedule to line up. I believe they are called "tunnels" and Cox can see them with a special tool if you call up and ask.

I have an Explorer Cisco 9865HDC, rev 3.7.  It's the 6 tuner Contour.  I don't see it listed on the page you linked, however.

I see a Cisco screen during a reboot.  The software revision is OHT3.3.0.2002.

My guide data and DVR schedule are OK.  It's only individual, recorded shows which exhibit the error.  I'd guess that about 1% have this problem.  Nothing I've been able to do (reboot, refresh, etc) changes their status.  

Hi Nichole.

I see no pattern to the recordings which fail.  They are on different channels. They seem to complete, according to the length of the recording.

I do not have any problem with recordings once they start playing, just at the very beginning.

Hey JohnRS,

Are you saying you get the error message at the beginning when trying to start the recording but once you let it play for a while it shows fine?

Hi SharielH.

This problem occurs only at the very beginning.  The recording does not play at all, then after a few seconds the error message appears.  There is no way to "continue" after that, so you can't see any of the recording.

P.S.  There appears to be a problem with the Forum notifications.  I'm subscribed to this issue, yet I haven't received any notices when new messages are posted.  Perhaps I've misconfigured something, but I've checked twice and the setting look correct.  My email address is correct (I get other email from Cox).

Please let us know if you do run into the issues with the double recordings, though the signal may still be a possibility it is less likely. As the SD and HD channels do use different frequencies. 

With the forum notifications they are turned on with the forum, if you have verified the email address there you may want to check that the emails are not getting filtered to a different folder or spam.

Forum notifications stopped working for me two years ago.

Hi Ed.

Unfortunately I was hoping to double record the same channel.  But I see that I can't do that.

I receive other Cox mail (monthly billing) but nothing from the forum.  Nothing in my spam folder.

Hi scottinphx.

My first DVR was a TIVO.  I guess it spoiled me.  I only found one bug with it, and they fixed it 2 months later.

Contrast that with the Cox Contour.  It's obviously never been checked by a QA person.

Streaming looks better and better each day that passes. 

Hi EdwardH.

I did get the forum notice for your message.  Thanks!

Yes, but recording the same show on different channels would prove anything about the signal level, unfortunately.
