You'll probably need to look at the HDHomeRun config utility while it's attempting one of these failed recordings to see what it's recording - like the channel is marked copy-once, or not locked, or the cable card is having an issue, etc.
I'm looking at that page for tuner 1. I don't see any relevant fields for a channel I know causes problems. There is a "Copy Protection" field on the overall status for the tuner which is set to "Copy Free". But that's an all channel value. Should I check the other 5 tuners?

It's not about the tuner ... it's about the channel.
Have NextPVR record a show on a channel that is a problem. View the Ceton webpage while the recording is in progress to see if the Ceton reports any issues.
For the moment, I can't reproduce it, even on the channnel that previously reliably had the problem. But I doubt it's gone. Recently a show on another channel stopped recording early. Something is going on.
After a lot more failures, I've concluded the problem only occurs for a few seconds at a time. In one case, when I saw a show (in that case, a 480i show) failed to record, I was able to switch to the channel that would've been recorded before the show in question was scheduled to end. The channel played live just fine. So I suspect even a few seconds is enough to cause NextPVR to give up recording the show. At times, roughly 1/3 of the shows either fail to record at all (a file of 0 bytes is created) or the NextPVR stopped recording early, but still managed to record part of the show.
I suspect it's more of a case of some specific behaviour of the Ceton device. NextPVR will wait for the entire time of the recording for data to be delivered. Most devices will resume sending data after a signal outage is restored, and the recording will happily continue. Maybe the Ceton doesn't do this, and just gives up.
