Unhandled Exception Error when changing TV Channels

[Bobbybear]

Hi Sub
I have applied this patch but I'm sorry to say it does not make any difference.
The problem still occurs.

[sub]

Is it still that same message?

System.NullReferenceException: Object reference not set to an instance of an object.
at NextPVR.Players.BasePlayer.ClearOSD()

It doesn't look like it'd be possible to get that error any more.

Hi Sub
I re-created the message and pasted it here.

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.

What date/time is your NextPVR.exe file?

[Bobbybear]

Hi Sub

07/12/2017 23:05

Your request prompted me to see if there is a later version.... I do try to keep up to date.
Found the release from 8th December, will install it and try again.

[sub]

That updated NextPVR.exe I posted for you on the last page was dated 28th Jan 2018, so you obviously didn't install that correctly. You need to overwrite your existing nextpvr.exe with that new one.

[Bobbybear]

Hi Sub

I have tried this a couple of times and something unusual happens.
Stpo Recording Service then.
If I double click the .exe file nothing happens!!
If I right click then Run as Admin the cursor changes to working in background for a few seconds and then stops!!
Nothing more happens.
I have disabled Virus protection (JIC) but no difference...
Is there a problem with the .exe file?
NPVR usually installs just fine for me

[sub]

It's not an installer. It's an updated nextpvr.exe file. Drop it in the C:\Program Files (x86)\NPVR directory, replacing your existing file of the same name, then run NextPVR the same way you normally would.

[Bobbybear]

Hi Sub
I just thought about that in the shower (where I do my best thinking)
I'm so used to having NPVR as install files I just did not think, I will remeber for the future.
You will be pleased to know the new .exe file works just fine, no exception errors now when changing from HD to SD and back.
Many thanks for all your efforts.
Bob
