Query: Rubbish

I have tried both the DVD-R and the DVD+RDL blank discs purchased through the Amazon but neither works. Neither my DVR-MC1 Direct accept or recognise them nor my Pioneer player. Neither our HPMedia Center PC m7250n recognise the discs. So far they are a waste of money and completely useless. However, the TDK-DVD-R and Ridata DVD-R bought locally at Fredmeyer and locally made home videos on TDK or Memorex DVD-R or DVD +R work very well with all the machines I use.
