NextPVR Forums - Cannot Record Two Simultaneous Programs

Pages: 1 2 3 4

Every time I try to record two shows at the same time, Nprv seems to crash and generates a crash.mdmp file. Single recordings seem to work okay. I have included the logs and dump file in case this helps.

What type of tuner?

sub Wrote:What type of tuner?

Oops, sorry - guess that would help. I have an HR Homerun tuner recording over the air (ATSC). The OS is Windows 7. I disabled UAC thinking maybe this was the culprit, but it still fails.

Sub,

I forgot to mention that after the failures occur, the recording screen gives the same message that many other people have described - "Recording service not running at recording time", and that the recording service then needed to be started (the error appeared to have stopped it).

Since no one else has similar reported problems, I decided the issue had to be related to my setup. So I decided to bite the bullet and reinstall my system from scratch. The system itself is a Zotac dual core atom processor with Nvidia ION graphics, operating system is Windows 7 ultimate.

I just finished the reinstall and tried my first test at recording using Nprv. I started two Quick recordings from the TV Guide screen, one right after the other. Both shows on the TV Guide screen turned red to indicate they were recording. The first recording appeared to start normally and recorded approximately 30 MB of data before hanging, the 2nd created a directory for the recording, but did not even create a zero length file for the recording itself. I tried to view the status from the ntay.exe menu but it would not display. I went into settings for Npvr and tried to show the status from there, and this hung the NextPvr.exe application. I checked the Nrecord.exe service and it was still running, using about 2% cpu utilization, but nothing was being recorded. I tried to stop the service, but received a message that the service was not responding. I have attached the logs but it doesn't look to me like they contain anything useful to troubleshoot the problem.

Is there a way to increase the logging level in Npvr or anything else I can do or provide to help figure out why I cannot record?

Note: Unlike previously, there was no system crash, system just hung. When I did restart the system and went into the recordings screen, both recordings had the message that the recording service was not running at recording time.

Not sure why I didn't think of this last time, but I decided to swap the priority of the two tuners in Npvr setup so that the first recording would occur on the 2nd tuner. I did this and attempted another recording, the recording never started and the recording service stopped.

Both of these tuners work fine in GbPvr so I do not think it is a hardware problem. Once again I posted the Nrecord.log file. Next I will try rescanning the channels on the 2nd tuner and see if this makes a difference (the 2nd tuner was setup as a copy config from the first).

Hmmm. I just restarted the recording service so I could rescan the channels (I did this before the previous failed recording was over). When the recording service was restarted, the previously failed recording started recording successfully on the 2nd tuner, so apparently the hardware is not a problem. Now I am more confused than ever.

I was able to reproduce this repeatedly (3 or 4 times) although sometimes the recording service would hang, other times just stop. The last time it hung, and when I tried to stop the service I got a Microsoft .NET Framework unhandled exception. Just in case it helps, the text was:

Do you have dynamic tuner allocation enabled in the HDHomeRun setup?

Yes, I do. Is that the correct setting? I also have the application set to GbPrv
