  Previous default from DScaler: 0x1c1f0008

  28: PREVREMOD = 1

  Digit 7: 27-24 (0xc = 12 = b1100 )
  27: COMBALT = 1
  26: PAL_INV_PHASE
    (DScaler apparently set this to 1, resulted in sucky picture)

  Digits 6,5: 23-16
  25-16: COMB_RANGE = 0x1f [default] (9 bits -> max 512)

  Digit 4: 15-12

0x47 is the sync byte for MPEG-2 transport stream packets.
Datasheet incorrectly states to use 47 decimal. 188 is the length.
All DVB compliant frontends output packets with this start code.
