I have been burning discs for about 4 years now and I have learnt 2 things.
1. Stay away from Yamaha burners. Seem to be very fussy about what they will and wont write to. Although I think Yamaha dont make any drives any more.
2. Stay away from Marlen ( or Marlin - the font makes it hard to read ) discs. I bought a pack of 10 and I have just binned most of them as they became either unwritable or forgetful.
