Realtek 2840 (DVB.C) support

It looks a lot like the driver is not working right. Can you use Device Manager to uninstall (ticking the box to delete the driver) and then do a re-install of the device driver. And as Kiwi says ... it might be worth trying a driver install via Device Manager.

i tried and still not works

HI,

This a little program to switch DVB-T/T2 <-> DVB-C for Astrometa tuner. It's provided as is.
Program :https://mega.co.nz/#!TQ8RgQxS!AUSwKpeqkv...PFv62Mk8Hk
Source (C#): https://mega.co.nz/#!7UMD2boS!yzOguViExl...BFEBDU0Ioc



To do if I have time :
- reset the device in an another thread
- Stay in system tray ?

I tried to set to DVB-C, but npvr device type is still DVB-T

Sorry, i don't know NextPVR...:o

In DVB-C or DVB-T/T2, the tuner has the same GUID, so you need to have two configuration.
One for DVB-T/T2 and one DVB-C. The "tune request" is not the same.
I try with different programs and my switch program work.
I don't know how NextPVR find DVB card but my own can do this (more information at http://sourceforge.net/p/directshownet/d.../3205a0a9/).

I provided the source for the "how to".

I also submit my program at Astrometa support. They reply me :

Dear Hervé,

Thank you very much for this very useful utility.
It should be much faster than re-install driver. (though It is fixed to re-configure DVBT/C in build 140529)
I have passed this codes to our software team for reference.
I think you may also share this with other users, I believe they will find it useful.

Best Regards,

Support
Astrometa

so I hope Astrometa will provide a similar tool for the next drivers release.

If you are under Windows XP try to run as administrator. I force UAC, but it's only available for Vista and newer.

I run it on Win 8.1 as administrator.

I install NPVR and i can confirm there is a bug. My little tool work with DVBViewer and ProgDVB but not work with NPVR

It works with every BDA compliant DVB-C I've used. I can only guess there is something odd or quirky about this device's drivers.

If you can view the Settings->Devices screen, then post the c:\users\public\npvr\logs\npvr.log, I'll check what it says about the devices it detected.

According to this output, the driver doesn't have a 'KSNODE_BDA_QAM_DEMODULATOR', which a DVB-C device would have, so has far as the app can tell, this device doesn't support DVB-C.

However, I've attached a patch which ignores this and assumes 'ASTROMETA DTV Filter' does have DVB-C, even though the driver doesn't claim to support DVB-C.

This shouldn't be happening.

What u should make sure is that u install the appropriate driver for DVB-T2 or DVB-C as appropriate.

For DVB-T2, use the following:

For DVB-C, use the following:
