Ups...sorry for the incomplete Mail...

Nice:)

If you like some little bit faster tuning, you could try to remove the afc
correction from ves1x93.c

In ves1x93_ioctl:

 case FE_SET_FRONTEND:
 {
  struct dvb_frontend_parameters *p = arg;

  tuner_set_tv_freq (i2c, p->frequency);
  ves1x93_set_inversion (i2c, p->inversion);
  ves1x93_set_fec (i2c, p->u.qpsk.fec_inner);
  ves1x93_set_symbolrate (i2c, p->u.qpsk.symbol_rate);
-  ves1x93_afc (i2c, p->frequency, p->u.qpsk.symbol_rate);
+ //  ves1x93_afc (i2c, p->frequency, p->u.qpsk.symbol_rate);
  state->inversion = p->inversion;
  break;
 }

I think a dvb_delay(50); in ves1x93_clr_bit() is enough to make shure all
demod internal afc corrections are done...
