When I play CD-Rs on my Solo I usually get a glitch in the first few minutes, but then it plays OK. It doesn't always happen, but I have accepted that it is probably because the Solo is not designed to play CD-Rs, and it was the price I paid for playing my (legally) downloaded music. However, it occasionally does it with commercial CDs too. Is it a fault or are the transports a bit temperamental and picky about what they play?
