Inconsistent scan device result in Windows 10

[tamcy]

I have two dual-tuner TV cards installed in my PC. This means that normally I should see 4 devices in the device listbox.

This works flawlessly in Windows 7 and 8.1, both for DVBViewer and recording service.

My use case: Device #1, #2 and #3 assigned to the Recording Service, and let DVBViewer use the "Unicast Network Device" (connect to RS) and the #4th device when necessary.

 

But things got strange after upgraded to Windows 10.

 

As said, I should see 4 devices on the device list. However, in Windows 10, every time I press the "Scan Devices" button, the result is not the same. I observed cases when there is zero, 1, 3, or 4 devices found.

 

I can keep on pressing "scan devices" button until all 4 devices are found, and leave it as is. But this won't work, because when 4 devices are found, changing channel will have no effect, making the app unusable. Switching channels seems to work only when inadequate devices (1-3) are found.

 

This make me wonder: What if I disable other devices when 4 devices are found, leaving only one usable by DVBViewer? I tried, and switching channel works! Enabling the second and third device, DVBViewer still works. Then I enable all 4 devices, and switching channel failed. At this time, disabling other 3 devices again won't help anymore - I need to start over and do the "scan devices" process again.

 

Of course, I can compromise and work with only 3 devices. But as I said, I use Recording Service most of the time, and the situation is actually worse in Recording Service - I can only see zero device found when I click "scan devices".

 

Although probably not helpful, I attach the screenshots of inconsistent devices found when pressing "scan devices" for your reference.

 

I tried reinstalling DVBViewer but no difference.

Thanks in advance!

Oh, I should attach support.zip. Here it is. And some more system info:

Thanks.

Have you tried to install update TV card driver which is designed to work in Windows 10?

 

And there went something wrong with the support.zip
