Technically, the jukebox is not supposed to play burned CD's. It was designed to play commercially manufactured CD's.
you are correct assuming a cdm 12 pro(which is common) in the wp100,i operate 10 of those machines
i find the 12 pros sensitive to the quality of the cds or cdr's used...
if u must use cdr's get good ones and burn them at a slow speed(less byte errors in burn)...
but if u r getting a skip issue on (real) cd's u may have a faulty player..
a good clean and lube may fix if the laser is good
rowe sells a lube kit for cdm 12 pro players(u may have to contact a distributor to get one though)
