Unable to find available capture device.

[Strontium_99]

Hi there.

I've got a Windows 10 PC running NextPVR 3.9.2.(161119) using a Hauppauge PCTV 290e DVB-T2 receiver.
Everything was running fine until I had to move things around in my lounge, which required me unplugging everything and reconnecting it.

Now NextPVR won't record anything, and if I try LiveTV I get the message "Unable to find available capture device (Unable to locate tuner filter (PCTV 80e/290e/460e BDA 2875 TVTuner))".

I've reloaded NextPVR, gone into Devices, removed all devices and set them up again. It seems to find the Tuner ok and even finds the channels. In devices I now have this listed:

Type Device Present Enabled Channels
DVB-T PCTV 290e/460e BDA 2875 TVTuner Yes Yes 157
QAM PCTV 80e/290e/460e BDA 2875 TVTunerC Yes Yes 0
IPTV IPTV Device Yes Yes 0

I've tried disabling both the QMA and IPTV devices but still get the same message.

I've attached a log file, hope it's the right one needed, it's the latest.

Any ideas please?

Big thanks.

Ok. Doesn't look like I can attach the log file, so I'll copy and paste it instead:

[Graham]

It may be that NextPVR has "reinstalled" the tuner as a "new" device with "new" channels. It may be that you now have a bunch of "old" channels that point to a tuner that has been "uninstalled".

Do you have duplicate chennels in Settings --> Channels ... Can you delete all of the channels in Settings --> Channels and then rescan to get the channels back in Settings --> Devices?

PS you need to zip the log files to attach them to a post ... There's a button in Settings --> About.

Hi Graham.

Think you were onto something there. I deleted all the channels and re-scanned for them, and after a little tinkering, managed to get it all working again.
Thanks for your help.
