Channels not being detected

Added by Ohad Benjamin almost 12 years ago

Hi,
I am trying to setup a DVB-T USB Tuner on my Raspberry Pi running OpenElec.
I should begin by saying that the device works on Windows 7 with BlazeVideo HDTV Player 6.6.
The program scans and finds the TV channels and the Radio channels that are available.

The OpenElec version is 2.99.1.
Linux openelec 3.6.11 #1 PREEMPT Thu Jan 3 01:11:11 CET 2013 armv6l GNU/Linux

The device is recognized when I issue the command lsusb:
Afatech Technologies, Inc. AF9015 DVB-T USB2.0 stick

Tvheadend also recognizes the device (I see it in the list when trying to configure).
When I use the "Add DVB Network by location..." button I add il_all (Israel) and 2 muxes are added.
They both start out with 100% quality and then they get to zero.
Once the initial scan is over there are no services available which results in that the "Map DVB services to channels..." button is grayed out.
I also tried adding the 2 muxes manually (538MHz and 514MHz), but since I don't know the configuration I set all the parameters to Auto and the bandwidth to 8MHz.

I tried using w_scan which resulted in:

Info: using DVB adapter auto detection.

Anyone has any idea?

I dried this same thing on my Ubuntu machine, and the same thing happened.
