Unhandled exception

[crankdoofus]

Hi folks,
NextPVR was working very well for me until recently. I've started getting an unhandled exception error when I perform a particular sequence of actions : open the UI, watch one channel, close the channel, click on another one in TVGuide, an unhandled exception is thrown with the details as below. I've attached the logs to this post as well.

Some extra pieces of info: I installed TV Listings recently, and tried removing that to eliminate it causing the issue. I think I've managed to clean it up and it doesn't show up anywhere. I upgraded to 3.9.2 recently as well and tried going back to earlier version to see if that was the issue, but of no help.

Any suggestions/pointers will be helpful !

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I just had a quick try at reproducing it, but didn't see the problem.

open the UI, watch one channel, close the channel, click on another one in TVGuide, an unhandled exception is thrown with the details as below

When you say "close the channel", what exactly did you do? Was this pressing the stop key on a remote, or Ctrl-S or something else?

[crankdoofus]

Thanks for your reply.
By "Close the channel", I mean shutting down the channel, to come out to the TVGuide.
I think this has something to do with the TVListings plugin. I removed it by deleting it from Plugins.
I also tried to delete the C:\Program Files (x86)\NPVR folder and re-ran the installer, but the problem is persistent. Is there any other information that I can provide. I can make a video of the steps I do, if that helps.

I also installed Kodi and Sage recently, have been trying to get an HTPC configuration working, do you think this might be related to that ?

I think that Sub is asking how you shutdown the channel ... Do you press a button on the remote to go back to the TV Guide and which button? Do you click on the screen using a mouse and what do you click? Do you press keys on a keyboard and which keys?

[crankdoofus]

oh ok, initially I was closing the channel by clicking on the stop square (from the controls above the program description) using a mouse. I tried CTRL+S too, with the same results.

Did you try changing from the LAV video decoder, it is a poor choice with NextPVR.
