Hi, I spent several hours trying to configure NoElec R820T DVB-T RTL2832U USB Dongle
I am running: Ubuntu13 x86_64, Kernel 3.8.0-19-lowlatency
I'ved git clone git://linuxtv.org/media_build.git, ./build, installed, rebooted, mprobe modules,
load unload. The follwing outputs of w_scan, lsusb dmesg and lsmod are listed here.





$dvbscan /usr/share/dvb/dvb-t/auto-Default

$lsusb | grep RTL
