DVR recording "stopped"

I have an HR54 and I've seen it a bunch of times now, where a scheduled recording ends up being only a partial recording and the reason the DVR gives is that it was "stopped" as if someone manually stopped a recording midway through it, but that is impossible in my case. What's up with this and can it be fixed?

 

Doesn't sound like my issue. The program was the Nuggets/Blazers NBA game on TNT. the program guide said it was going to be 2.5 hours, and I added an extra hour cause it was a live game like i always do, but this time it only recorded a total of 38 minutes and said someone "stopped" the recording in the home, but i was the only one home and only one that has access to the DVR. The DVR was fine, wasn't unplugged or restarted or anything. It was just totally random and this isn't the first time this has happened.

 

I can try that, but what will that do? I want to make sure nothing gets deleted?

 

no. private single family house and it doesn't happen often, but it does happen.

 

but if a box randomly reboots, then it automatically starts recording as soon as it turns back on. And in my situation, it never rebooted anyway.

 

because i have had other programs record in the same time period without any interruptions.

 

I did a system test and everything was fine : "System Test Results All Items Ok"

Then I attempted to restart the receiver to perform the BiST test and got this warning message :
"Tuner Conflict: Restart this receiver
Once the process you've requested begins, the following scheduled events will be canceled : Trail Blazers @ Nuggets 7:30p 245 TNTHD
Are you sure you want to cancel the event(s)?"

What's interesting about this error message is that it's incorrect. That game was YESTERDAY and that was the recording in question here that was only partially recorded and "stopped" by someone as it claims. So something bizarre is happening.

Anyway, I continued with the restart and then it gave me this message "Alerting network, please wait" and it began the reboot process.

I hit Select when you told me to and nothing happened, it just completely ignored it and rebooted the box as usual... Just in case, i tried another restart, hit the Select button several times this time around, and again, ignored it and rebooted as usual...

 

does that just mean the dvr is connected to the internet? why is it occupying a tuner? and is this related to the recording stopping?

 

All i have is HR54 and C61K

 

Thanks, so how many total tuners do i have to record programming simultaneously?
