problem happened again.

NPVR worked nicely for the last two days, now its has the same problem. This time however I have captured the error as printed by the internal server:
Server Error in '/' Application.
Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Now I guess I do not have to hit the CPU with a hammer to replicate the problem.

The PC was turned on 3 hours in advance of the time for the EPG update to happen which gave NPVR one hour to complete the update. When if works normally, that takes 20 minutes.

The EPG updated the first 10 or so channels, then failed.

On Win XP.

What to do now? Delete and reinstall NPVR yet again?
Maybe it will behave itself if I ignore the EPG and just do everything as manual recordings??

It does the error now each and every time I dare to click 'manage recordings'.

Run a browser remotely or locally... same thing.
Reboot and try again, same thing.

Been though this before. The only fix was remove it and reinstall with setting up all over again. Otherwise it fails forever.

I did install the latest patch to NPVR as well during the last reinstall.
I hoped that would have fixed it.

Sorry if some are so 'sensitive' to my complaints.

Bottom line, something is wrong with NPVR or SQL. I have read plenty of posts on other forums where people are still using very unpolished abandonware to simply send commands to the tuner card to record channel so and so at X time because the EPG thing will cause you to lose the recording unless everything works just perfectly, first time, every time.

They are doing that because of these strange little quirks in 'modern' PVR software that causes failed recordings.

IMO, NPVR is the best available software to do the task in a way similar to MythTV using windows.

It would be nice if was as reliable as a short function that simply accesses the card using a scheduler without any bells and whistles.

I now assume that my post will once again get closed.

Stop reinstalling this Will Not fix the problem
Upload your logs when it happens with explanation
someone will then be able to see whats going wrong
are you sure your .net stuff is installed right (updates etc)

Thats if your serious

[mvallevand]

It seems your problem is with NEWA not NextPVR, but as stustunz and I have written reinstalling won't help. Maybe try the command line scheduler http://forums.nextpvr.com/showthread.php...=scheduler

If your problem was with the EPG update, then post the logs showing the EPG update.

FWIW, I get this error, too, when I mess around with NEWA, just haven't had a chance to try and make sure I was doing everything okay. I read the previous thread and didn't get that he was trying to run the web interface.

If this is happening in NEWA, you need to add the "\" to the end of the VLC config setting from the NEWA config page. Open NEWA, click on the Config tab, scroll to the bottom of the config page and look for the "VLC Location" fields. (There are two, one for Video and one for Audio. For 64-bit Windows the values should be "C:\Program Files (x86)\VideoLAN\VLC\" That trailing backslash has to be there or NEWA throws up when you try to stream video. It would be nice if NEWA provided a more useful error message when this happens.

I don't know about the OP, but I tried this and it helped with the streaming, but I still get the error he mentions when I got to "Manage Recordings" in the CSS version (http://localhost:8866/Manage2.aspx).

I should note that I DON'T get the error if I use the HTML page, http://localhost:8866/Manage.aspx

Have you applied this patch?

Have you applied this patch?

No, I had not. Applying that fixed it. Thanks.

My only excuse for not having seen this before is I started with this thread before it was moved, and hadn't seen the other thread since I hadn't seriously been working on this error. Weak excuse, I know.

Thanks again.

No problem....thanks for letting me know it fixed it.....it will be in the next NEWA release.
