Hi all - I have no problem using the built-in burn facility on this Vista laptop, to create mp3 discs, that then play in various external machines. However, my partner has a Pure digital radio/cd player, that she only bought this week, that claims to play cdr and cdrw discs, actually, it said minus cdr [I'm not sure what the difference is on that one], but each time I burn a disc and try to play it in her machine, it says "format not supported." The DVDRW drive on my laptop uses UDF, but I wouldn't have thought this would be an issue with today's players? Anybody help me out please? - Andy
