NPVR Crash

[Bobins]

Unfortunately my previously reliable NPVR server suffered a power problem caused by a failed power supply fan & overheating and the result of the abrupt power outage corrupted the system disk.
I did have a backup to recover from but it was 2 years old so somewhat out-of-date. [Lesson learnt :-( ]

Having recovered the system disk and updated everything I could think of (including re-building the recordings list), I once again have a working media centre.

The above said, I'm now seeing regular NPVR crashes when a recording has finished being watched.

I'm using the TV Listings plugin and it is the latest version.

Any ideas where to start looking?

The system error log shows:-

This is on 3.9.2 as I'm holding off upgrading till the latest version has had some time to become stable.

I sadly had to give up on TV Listings in the end due to very similar issues.

You could try creating a shortcut to NextPVR.exe and adding -no3d as a command line parameter and see if that helps.

btw, the latest version is totally stable for me, I just have a slight issue when skipping when the video takes a second to "spool up" but otherwise it's fine.

[Bobins]

Thanks gED.

For me, TV Listings was always OK, it's only since restoring and updating NPVR that the problem has started.

The NPVR logs didn't seem to give much of a clue as to the problem but I have noticed the following...

This is confusing me as the default Recordings menu isn't enabled and the only place I can find a reference to ListSelectionMetaData is in the default Recording skin xml file

[gEd]

yes, to be clear, my similar problems started after upgrading NPVR. There is some incompatibility with it and TVL that never got fixed afaiak.
iirc , I had ListSelectionMetaData messages even when it was working fine.

Not here there isn't. I have used TVL throughout without problems. There was an incompatibility issue that was fixed by a TVL update last year. My suggestion would be to completely remove TVL and re-install from a fresh download.

Definitely worth trying with "nextpvr.exe -no3d"

[Bobins]

Thanks Sub (& gEd).

Now you both mention it, I seem to recall I may have added that switch some time ago to the original system but obviously it would have gotten lost when I did the restore from the old backup.
Switch has been added and just looking for less cursing from the better half now as an indication of success ;-)

Still seeing a lot of these in the NPVR log:-

I can't find any reference to these in the default skin XML file for TV Recordings or TV Listings. I can find a reference to "ListSelectionMetaData" in the Recordings XML file but can't see the "PopupCenterButtonSelected" anywhere.

Are these errors likely to be elements missing from the TV Listings/ TV Recordings skin xml files? (and if so is there any way to find out what needs to be added?)

[sub]

Those aren't errors. It's just saying the skin isn't using some option skinning features. Just ignore these log messages.

[gEd]

Not here there isn't. I have used TVL throughout without problems. There was an incompatibility issue that was fixed by a TVL update last year. My suggestion would be to completely remove TVL and re-install from a fresh download.

I tried a clean install of the plugin, having first deleted the old folder and same issues as before (and as the OP). I haven't tried again with -no3d as I recall that this didn't give me total stability either. Also alibert isn't really around anymore (iirc) to support it.
I'm disappointed that it doesn't work for me as I have been a long time user of it and really like the additional features and it's layout but meantime, Subs standard modules have caught up in several respects also since TVListings was first launched.
