Can two of the same mid cause problems

hello guys and girls messing about with my litey this morning and media code speed edit i dumped my firmware and found when i opend it in mcse that it had this

 
TYG03           16x,12x,8x,6x
TYG03           20x,18x,16x,12x,8x,6x

can this cause conflicts in write stratigies :confused: just some info as wether or not to keep it there or not would be appreciated :slight_smile:

Perhaps, just a guessing, 1 for OverSpeed OFF and the another 1 for OverSpeed ON

theres no other double codes in the firmware :\

TYG03 is not the full MID which is countingโ€ฆ
