Re: Support for Terratec Cinergy 2400i DT in kernel 3.x

[Patrice Chotard <patrice.chotard@sfr.fr>]

Hi Frédéric,

Two patches have been already submitted and are available since v3.7-rc1

media] ngene: add support for Terratec Cynergy 2400i Dual DVB-T  :
397e972350c42cbaf3228fe2eec23fecf6a69903

and

media] dvb: add support for Thomson DTT7520X :
5fb67074c6657edc34867cba78255b6f5b505f12

Reading your logs, everything seems OK, i think that with a plugged
antenna the w_scan should indicate that it founds at least some DVB-T
signals like these :

$ w_scan -ft -cFR
w_scan version 20120605 (compiled for DVB API 5.4)
using settings for FRANCE
DVB aerial
DVB-T FR
scan type TERRESTRIAL, channellist 5
output format vdr-1.6
output charset 'UTF-8', use -C <charset> to override
Info: using DVB adapter auto detection.
