[mythtv-users] Tuning problem with DVB-T card

[y_b]

Hello,

I am trying to get mythtv working with a Hauppauge Nova-t card.

I am under Mandriva 2006 (kernel 2.6.12)  and I get  mythtv  by urpmi.

I can watch all the channels using xine.

When I start mythbackend I get :

        mythtv at BYSE ~]$ mythbackend

When I test the default channel (#513) I get :

        [mythtv at BYSE ~]$ tzap "direct 8"
        using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
        tuning to 474000000 Hz

        status 1f | signal 0042 | snr fff1 | ber 0000000e | unc 00000000

I also can watch it with xine

Why mythtv cannot tune on any TNT channels ?
