Burning cd problems



Sorry to post two queries on the same day but I have been to a few forums and this one seems to be more imformative.My problem is that I have a Samsung 304b combo.It plays dvd’s ok but will not recognise blank discs when it comes to the cdr.I have tried various types of blank discs.I have thought about flashing it but I know it can cause irrepairable damage if it goes wrong and would I then be left without the dvd as well.To compensate for this I went and bought a Phillips JR24CDRW but I am having problems burning audio onto it.It will burn one track then stop.I am using the latest Nero software.I am starting to wonder if my computer is configured wrong.Any suggestions would be helpful.
