This problem I had using drivers 1.0.0.
I solved this problem patching drivers in this way :
file ....../DVB/driver/av7110/av7110.c
function av7110_video_ioctl

about at line 3045

/* only channel 0 has a tuner */
if(!v->tuner)
      return -EINVAL;

I changed with
/* only channel 0 has a tuner */
if(v->tuner)
    return -EINVAL;

And mplayer started work fine


anyway


Drivers version 1.1.1 have the problem solved inside
