Hello all, I have just recently joined the ranks of DVD burning and learnt that there are two types of TDK + - blank discs. Dick smith, big w etc sell spools of 25 blank dvds for around $34 or spools of 50 for $35. The 50 spool dvds are rubbish and muck up the 25 spool are far superior and play perfectly. When I checked my burners recommendations TDK was one of the disc recommended. When I asked a Dick Smith about this the assistant told me they are both the same. Then why the price difference? I made around 20 new coasters and have learnt my lesson in buying cheap!!!
