NRecord broken and I'm digging deeper...

[macgyver]

Hi all.
I've broken my system and in trying to fix I've dug myself into a hole.
My old XP system has been running 3.9.2 in 'if it ain't broke' mode for years but I finally started on an upgrade path. First thing on the list was to go all digital and replace my final analog tuner with an HD PVR2. Got a 2nd hand one, plugged it in and dowloaded and installed the Capture package (was going to just download drivers but the download link was inop.).
All went well at first, it installed and seemed to work but then I noticed a problem - my DVB-T device started to fail with 'unable to locate tuner filter (Hauppauge WinTV 88x DVB-T Tuner/Demod)' errors. Everything else seemed OK and at this point I hadn't done anything with the new HD tuner apart from add a single test channel. This was l yesterday so I left it to do it's best until today to investigate.

So today I've broken it completely as NRecord now crashes with no errors in the (attached) logs but these 3 errors in events:

An unhandled exception occurred and the process was terminated.

Things to note are:
When I installed Hauppauge Capture and rebooted an MS .Net security update was installed.
I have since uninstalled Capture - there was no change to original problem.
I viewed config.xml and devices.xml with EditPadLite but thought I had made no changes.
Deciding to dig myself in deeper I decided to install the latest v4 NPVR, which went OK but NRecord still fails with the above.

In summery I have two problems: firstly the installation of HD PVR2 broken my DVB-T tuner (drivers?) and then separately I edited something somewhere which broke NRecord. I need to fix the latter, which I'm hoping is a simple config issue, to then look again at the tuners.

Any advice would be much appreciated, I know I should be moving on to W10 - this was supposed to be a simple first step!

Cheers

OK. Had a break and a cuppa and now I'm back, slowly filling in the hole.
I've got it running again by re-installing Capture so I'm basically back to my original problem that my DVB-S and old analogue tuners work fine but DVB-T records result in 'unable to locate tuner filter (Hauppauge WinTV 88x DVB-T Tuner/Demod)'.

Presumably this is some sort of clash with the new HD PVR2 - do I need something on devicerules?

New logs attached.

Hauppauge provide hcwclear.exe that will remove all Hauppauge drivers and software ... Allowing you to start from a clean slate.

It does look like it's missing driver components in that filtercheck.log, so maybe worth running that hcwclear, then reinstalling the drivers.

Are you still using your PVR150? If not, I'd take it out of your machine.

Thanks guys.
I've just run hwclear (just for drivers), rebooted and re-installed the DVB-S, DVB-T and PVR-150 drivers. All installed OK (no issues in device manager) but I still get the same 'unable to locate tuner filter (Hauppauge WinTV 88x DVB-T Tuner/Demod)' when it tries to use the DVB-T device.
Bit stumped now - should I run hwclear to remove apps too? Do I need any apps installed?

... should I run hwclear to remove apps too? Do I need any apps installed?

It won't hurt to remove everything Hauppauge including the apps ... the only thing that you might need is SoftPVR perhaps if you are receiving analog content from a STB ... the NextPVR wiki has a page on SoftPVR so its easy to re-install just SoftPVR.

Can you post the current filtercheck.log and logs again?

[macgyver]

Thanks Sub, appreciate the help.
Logs and filter attached.

In that filtercheck.log:

- PVR150 looks fine
- Digital side of Nova-S looks ok (Hauppauge WinTV 88x DVB-S/S2 Tuner/Demod)
- Digital side of Nova-T looks ok (Hauppauge WinTV 88x DVB-T Tuner/Demod)
- Analog side of Nova-S looks non functional. (missing crossbar)
- Analog side of Nova-T looks non functional. (missing crossbar)

Do you need the analog side of these Nova-S/Nova-T devices? ie, the composite or svideo input

If the Nova-T/S is not working, can you run this version of filtercheck.exe. It gives more details.
