Gigabyte U8300 and NPVR

[leotzian]

Hi to all for this helpful forum, this is my first post. I have a strange problem concerning NPVR and my Gigabyte U8300 Hybrid Usb Dongle.
I had installed the software, the DVB-T section of the usb dongle had no problem channels were found all ok.
In devices list my Analog section of the card was not shown so I followed the wiki and installed intv7_cd_3.9g.exe, runned the bat file, but the analog tuner was still not shown, the I run filter check and I had added the lines in the AnalogDevices.xml as in the wiki, the analog tuner appeared in the devices, searched the channel, channels found, but I had black picture no sound.
Searching the wiki I tried all the decoders and the decoder that worked was ffdshow_rev4531_20140628.exe.
I use Windows 64bit.
My problem is when I run the analog tuner first ( try to see a analog channel ) channels are all ok, when then I switch to Digital channels channels are ok, BUT when I switch again in the analog tuner I have black screen, no sound.
When ffdshow is activated in the status bar I have 2 icons one for the video and one for the audio details in the first time in the analog tuner the details are shown, the same and in the digital but when i switch back in the analog black picture no ffdshow details.
The only way to make it working again is to reboot the PC or take off the dongle from the usb port and put it back again.
Restarting NPVR, stop and start NPVR service, or restarting Recording service doen't solve the problem.
Can you help me?
Thank you all in advance.

There is a button at NextPVR Settings --> About that will zip the NextPVR log files.

Please recreate the problem and then zip the logs and attach the zip file to a post telling us the time of the problem so that we know where to look in the logs. Thank you.

Unfortunately this is sounding like some weird quirk to the drivers on your device. I'm not sure what to suggest, other than maybe looking for different versions of the drivers in hopes that some other versions fixes this issue.

Hi my friend thanks for your help.
I tried to see live TV using NPVR server through Kodi, All are working fine all Analog and some Dvbt Channels that I had no picture using NPVR TV application. Also the composite input is working too.
Why I don't know but now are all OK.
Thanks for your help.

, All are working fine all Analog and some Dvbt Channels that I had no picture using NPVR TV application.

ffdshow has many settings. It may be that it is set to show H.264 and not show MPEG2 or some other setting is bad. You can see the settings in NextPVR Settings --> Decoders and click the button with three dots ... that is beside the decoder name.
