OK. I tried the CVS version, and by commenting out the DVB-S part of
ioctl_SetFrontend I got the tuning to work. (Well, at least it reports
that tuning was succesful.)

I think that it was the hiband assignments that messed up the frequency
assignment for DVB-T.

Here's what i snipped out from dvb.c

    // These won't be needed with DVB-T, JP - 02.10.2003
    
/*     /\* Set the frequency of the transponder, taking into account the */
/*        local frequencies of the LNB *\/ */
/*     hiband = (fep.frequency >= u_lnb_slof); */

/*     if ((ret=ioctl_SetupSwitch (p_input, front, 0, b_polarisation,
hiband))<0) */
/*     { */
/*         msg_Err(p_input, "ioctl_SetupSwitch failed (%d)", ret); */
/*         return -1; */
/*     } */

/*     if (hiband) */
/*         fep.frequency -= u_lnb_lof2; */
/*     else */
/*         fep.frequency -= u_lnb_lof1; */

I think there should propably be a test to see what kind of a dvb card
(DVB-T/S/C) you have, and set up the dvb_frontend_parameters structure
according to that?

I still have a problem, though. I don't get any output (video, that is..)
