Oddly enough, the remote initialisation of the DVR did nothing to fix the problem with it crashing when it tries to record. I come in tonight to find it locked up in the same way as before.
I’m not yet convinced that this is a hardware issue though. So I am not expecting the box they bring on Monday to fix this issue unless it is a different unit (or has fixed software on it). Others are also having problems with the Motorola DCH3416, and Comcast’s service in general by the sounds of it.
And, yes, that’s yet another visit (my third so far) from the Comcast technicians – I asked tonight if they can book recurring appointments so they can just come out the same time each week and fix whatever has failed since the last visit. At the rate they’re going, they may as well just park out front.
