LiveTV always crashes - Colossus

[aseibert]

LiveTV is crashing on me every time I start it. It usually goes for a few seconds but sometimes up to a few minutes before it dies with a Windows error "NextPVR has stopped working".

I've scheduled and recorded a half hour program that played back in it's entirety without a problem. If I am able to pause LiveTV for a few minutes before it crashes, it will continue to play back indefinitely once I unpause it. It appears that it is only unpaused LiveTV that will not work.

I'm running Windows 7 Ultimate 64 bit and NextPVR 2.15. My hardware is a Gigabyte 880GA-UD3H motherboard/AMD Athlon II X3 450 Rana 3.2GHz triple-core processor with onboard ATI HD4250 video and a Hauppauge Colossus capture card. I have all the latest drivers. The TV is a 46" Samsung UN46D6000SF 1080p 120Hz LED LCD using an HDMI input.

Apart from making sure I have the latest drivers for everything (video, Colossus, audio, LAN), here is what I've tried:

- I've tried multiple combinations of decoders. I've used the Microsoft video decoder and the one that installs with WinTV (currently using Microsoft's). I've tried the SAF6 decoders but am currently using the ArcSoft audio decoders.

- I've tried each of the video renderer options.

- The video is onboard and shares the system memory. It was set to "auto" in the BIOS so I changed it to a static 512Mb (which was the max allowed option).

- I've excluded the NextPVR directories (for LiveTVBuffer, etc...) from my anti-virus software (Microsoft Security Essentials).

The Windows event logs give me nothing of value apart from saying that there was an app crash for NextPVR. I cleared my NextPVR "logs" folder and crashed LiveTV to generate the attached logs. I'm looking for a solution or next step to try in debugging this problem. I've been at it for over 2 weeks and I've exhausted my ideas. Thank you.

Try creating a c:\temp directory, then reproduce the problem, and zip and attach the c:\temp\crash.mdmp.

sub,

I have a c:\temp but no crash.mdmp nor any other file is appearing there. I thought it might be a permission problem so I made sure all users have write access to that directory and I also right-clicked NextPVR.exe and selected "Run As Administrator" but still nothing. NextPVR is most definitely crashing out though. The window closes and "NextPVR.exe" disappears from Task Manager. Could I be doing something wrong that is preventing the crash log from appearing or is there anything else I can provide you to help diagnose the problem?

Thanks,
Alan

Is there any crash info provided in the Windows Event Viewer?

[aseibert]

Here are the entries in the Windows Event Viewer. The first part is from level "Error" and the second is level "Information".

Do you end up with a dump file in C:\ProgramData\Microsoft\Windows\WER\ReportArchive\ immediately after the crash?

[aseibert]

Yes, here it is.

Unfortunately that file doesnt contain the dump info I'm looking for.

Did you maybe get a c:\temp\frontend-crash.mdmp instead?

[aseibert]

I'm not getting anything in the c:\temp folder.

Bugger.

You might need to look into using adplus to force the capture of a dump file of the crash. I dont really know that much about this tool myself, but I know it can be used for capture a dump from a process that crashes.
