Hi, Juan,

I generated the lircd.conf using irrecord and values are quite different:

This is my file:

  name  CREATIVE_INFRA_LEO
  bits           16
  flags SPACE_ENC|CONST_LENGTH
  eps            30
  aeps          100

  header      10013  4941
  one           646  1839
  zero          646   598
  ptrail        645
  repeat      10048  2446
  pre_data_bits   16
  pre_data       0x8435
  gap          235244
  min_repeat      1
  toggle_bit      0

Compare with lirc_CVS/remotes/creative/lircd.conf.infracd

  name  CREATIVE_INFRA
  bits           16
  flags SPACE_ENC|CONST_LENGTH
  eps            30
  aeps          100

  header       9051  4625
  one           534  1707
  zero          534   588
  ptrail        490
  repeat       9039  2363
  pre_data_bits   16
  pre_data       0x8435
  gap          108434
  min_repeat      1
  toggle_bit      0

Curiously, irrecord couldn't adjust gap parameter coorectly by itself. But, I noted that each touch in a button made the action twice. So I multiplicated irrecord gap value by 2, fine adjusted it mannually and it worked. With that configuration, the remote is working perfectly, even if I press a button repeatidly (even fast).

By the way, the exact gap value output by irrecord was 119622.

Codes for the keys are exactly identical, don't worry about it.

Thanks
