A couple days ago I experienced a problem with my five-year old HD TiVo with Lifetime subscription. I went to watch something I'd expected it to record that morning, only to find that it hadn't been recorded. So I clicked around the TiVo menus and saw that my TiVo seemed to have forgotten it was a "lifetime" device. I saw a message saying that my account was expired or cancelled (I forget the exact terminology). I also saw that the menus shown to be were limited to a very restricted set of options. I'm assuming this is what people see when they don't have a paid subscription for their device or lifetime service on their device.
So I tested my network connectivity. The test was successful. I tried a service-connection to refresh my program data, and this failed. I logged into the website, and the website showed my device as correctly having lifetime service. So I rebooted my device completely - and only then did it register as having service. Again, I forced a connection to download the program data - and when I did that, it correctly downloaded the new data.
Next, I checked my season passes. Every one of them showed up as "None Scheduled". Apparently when my device lost track of its subscription, it stopped checking when to record season passes. I re-ordered the list by moving one item higher in priority assuming this would force the TiVo to re-schedule everything - and this worked as I'd hoped.
If I look back at the Recording History I see a number of items listed as "Not Recorded" or "Won't Record" and when I check the details the TiVo says these items weren't recorded because "it was scheduled with a TiVo Plus service feature." with instructions on how to upgrade to TiVo Plus via their website.
From what I can tell - I'm back to normal, but I've never had a TiVo lose track of its subscription/lifetime service before. Has anyone experienced this before? Is it indicative of a one-time bad download, or a larger warning that this device may be near its end-of-life?
