Missed recordings

[topperdude]

Hi,

I've been tweaking my GBPVR server over the past few days. The server now runs headless (thanks to VNC) for the most part and I successfully configured it so that it automatically wakes machine from standby in the middle of the night (~1am) to update EPG.

Last night, I scheduled a recording to start at 3:35am. This morning, I noticed the recording had failed. Going through the GBPVRRecordingService log file, I noticed two lines with the "Asking Windows to be awake..." one for the scheduled recording and the other for the Update EPG. UpdateEPG seems to have worked but the recording failed. :confused: Thoughts?

The server was non-responsive when I checked in the morning and had to be rebooted. It did seem to be have come out of standby but was not responding to any keystrokes or mouse movements (keyboard and mouse connected to the server) and neither could VNC connect to it. I also looked at this page in the wiki and wonder if that is what happened? Even so, I am confused as to why update epg works fine but recordings fail? :confused:

Thoughts?

Thanks,

To be honest, I've got no idea. It sounds like GB-PVR is successfully requesting Windows to wake up at the required device, but the machine is failing to wake to a fully functioning state. Some capture devices have problems with their drivers that cause problems resuming from standby/hibernate, which sounds like it might be the sort of thing you're seeing.

From experience, video drivers can do the same. I have found that my system was much more reliable when I changed over to hibernate from standby. It is a little slower to startup but not by much. Might be worth trying?

martin123 and sub - looks like it had better luck with hibernate than with standby, thanks for the suggestion, martin. Looks like the computer came out of hibernation just fine at ~3:59am for the 4-4:30am recording and GBPVR also created the folder for the recording, but for some reason there was no file in the folder. Have attached the log - this was the only log file that had any activity in that time frame.

Edit: Not sure why it failed to load the Conexant graph as indicated in the logs or what that graph would be used for and if it was the reason for the failed recording, but if I playback the same channel via LiveTV, it works just fine.

Any thoughts?
Thanks,

2009-01-01 03:59:02.126 ERROR failed to start Conexant Graph
2009-01-01 03:59:02.126 VERBOSE ERROR_NO_SYSTEM_RESOURCES

It looks like for whatever reason, the device was still in a non-functioning state when GB-PVR tried to use it.

Those are the sorts of errors I got when having standby problems. The driver having problems (or not trying) to handle recovery fro power off.

For me, a combination of earlier drivers, using Microsofts 'devcon' with gbpvrwake to restart drivers seems to have improved it a lot.

OK - some progress (I think)!

Followed the instructions here and installed GBPVRWake.exe & fullresume.exe. Scheduled two recordings - one on analog side of the hvr-1600 and one on the digital/QAM side, both shows starting and stopping in the same timeslot. The machine came out of hibernation just fine and recorded only the digital/QAM tuner show (YES!) ; but the analog side did the same thing as before - created the folder for the show and then gave the Conexant error as before.

Some more digging pulled up this thread. Looks like one person was able to resolve the Conexant issue for the hvr 1600 by running the HCWDriverinstall.exe tool and another person was able to resolve the same error for the HVR 3000 card by adding ENCODER_DISCONNECT_BUG=1 in the direct.ini file.

Any idea what difference running the HCWDriverinstall.exe file would make, especially if I am able to use the analog side of the tuner just fine currently?

Also, what does the ENCODER_DISCONNECT_BUG=1 line do? Even tho' it seems to have helped one person resolve the same error with the HVR 3000, not knowing enough about the HVR 3000 card I am trying to figure out if it would be applicable for the analog tuner on the HVR 1600 tuner?

Thoughts?
