On this page it says that driver shoud be in kernel, but when I connect it nothing happens. Maybe I should download some kind a program to watch tv on PC?
Yes the drivers for that are in the main kernel-modules package and should load automatically.
I’m not sure what exactly you’re expecting to happen when you plug it in - the only thing that will happen is that device nodes will appear in /dev/dvb/adapterN for some value of N that depends on what other DVB adapters you have.
Once the device is created then you may be able to use totem, vlc, or other video software to read from the device and manage it. Surely there are apps available that will manage the tuner on the device so it can be used.
You will need to look up what is available.
A quick search for “how to use pc tv tuner” gives a lot of info – some for windows and some for linux, Some older and some more recent.
More detailed info was given with a search for linux software for pctv nanostix 2 tuner
Myth TV is one of the software packages that have been around for ages to support those tuners.
I still cannot to make it to work. it is recognised and working, but how to scan for channels and with what program to watch?
On VLC I am selecting capture device > tv digital > DVB-T or T2 > multiplex frquency 690 KHz > Bandwidth 8 MHz and it seems it connects, but how to look for chanels?
Help ! : D
You need one of the apps that allows managing that tuner.
mythTV, Kaffiene, Me TV, TVtime, and others should work.
Search online for an appropriate app for linux.
I’d start by installing v4l-utils and dtv-scan-tables and then using dvbv5-scan from the command line to try and find some channels.
Look in /usr/share/dvbv5/dvb-t and see if you can find a file for your local transmitter and then try scanning with:
dvbv5-scan --adapter=0 uk-CrystalPalace
but replace uk-CrystalPalace with the appropriate file for your transmitter.
