I can test the tuner with a RPi3 and raspian buster, but it doesn't recognize well the tuner. The raspian buster uses the kernel 4.19. Then, I update the kernel to 5.3 using the command rpi-update (rpi-update - Raspberry Pi Documentation). The first time work perfect; however, after reboot only appears the DVB-T #0. The solution was unable the RTL chipset and enable again as Cabala (thank you!) explained.
I'm using in Colombia with VLC media player in windows.
