V4 to V5, issues

[Stanno]

Hi all,

Finally took the plunge and upgraded v4 to v5 last weekend and have been having some issues.

The upgrade went reasonably OK, lost some pending recordings but was able to fix all that and have had a number of successful recordings.

I am running a very simple setup with a Win 10 Intel NUC receiving the aerial feed via a USB DVB-T tuner and out to a TV via HDMI, I use the NPVR windows client to set and play my recordings.

I am occasionally getting some sound stuttering when I first play a recording and when I skip forward, this is is not present when I play/skip the same recording in media player.  I saw another post about this and sub said there would be a fix for low power machines in the next release so I am hoping that will fix this issue.

I am also seeing slow scrolling in recording lists; the old v4 client scrolled through very quickly but v5 seems to almost pause before moving to the next item.

The main issue, when scrolling, is that twice now the client has hung.  Nothing works, not even alt-ctrl-del.  I have to press the power button to switch the machine off.  Each time this has followed a scroll down the ready recordings list and the last few items did not display the relevant poster on the right-hand side of the screen.

Logs attached, any thoughts/comments/advice appreciated.  Thanks.

The npvr.log is full of ...

It might be that you are missing a library or something but I have no clue what you can do to fix it ... You could try rerunning the NextPVR installer ... Someone that actually knows something useful will be along soon.

I have been trying various options and am now totally baffled and I hope that someone will be able to advise and help me out.

I have installed various media players and played the same file in all of them. It plays fine in MS Film & TV app and Media Player Classic. It stutters and the video and audio goes out of sync in Windows Media Player, VLC and NPVR.

I have no idea where to go from here so any suggestions gratefully received.

Thanks,

Can you post another set of logs after restarting nextpvr.exe? I'd like to see NextPVR starting up, but it's not included in the previous set of logs.

Hi Sub,

New logs straight after a start-up attached.

I have made some progress on the stuttering, I found an earlier post about screen resolution and I reduced mine, this has almost removed the stuttering.

Thanks,
Stanno

Ah, those logs don't appear to have any of the Direct2D error message your last logs were filled with. I guess that's good. It could have been the resolution was too high for you video card to successfully work with. (like unable to allocate large Direct2D textures etc)

Other than that, there is nothing obvious that stands out in those logs.

Thanks for reviewing sub.

I will try scrolling up and down through the Ready Recordings list (that's where it hung both times) now that I have altered the resolution and see if it happens again.

I have been on the higher resolution ever since I started using NPVR v4 several years ago; it is interesting that this started after upgrading to v5.
