Hi Ibrahim - When I insert a disc, the "burn a disc" wizard opens, and I am offered today's date as a name for the disc [obviously I can choose to change this] then when I hit tab, it says: "prepare this blank disc" choose file format, where the choices are live file system, and mastered. I always choose mastered, because it says they are playable on all computers, and in some CD players, where as the live format says the disc will be like a USB flash drive, where files can be added and erased. So, how can I get round this? If when I insert a blank disc, it's properties says the file format is UDF, then is it possible to change this to a format that cd players can play. Surely, when it says a clock radio can play CDR and CDRW discs, it should also say, as long as the discs haven't been written using a burner that uses UDF as it's formatting! - Andy ----- Original Message ----- From: Ibrahim Gucukoglu To: access-uk@xxxxxxxxxxxxx Sent: Sunday, August 26, 2012 9:04 PM Subject: [access-uk] Re: Burning discs to play in a CD player Hi Andy. UDF isn’t supported on most mp3 compatible CD players, it has to be a direct write I’m afraid. Make sure the option to use the disk as a flash drive is not selected as this creates a UDF formatted disk. All the best, Ibrahim.

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
