I have had a LiteOn LVW-5026 DVD recorder for 5 years or so and have not had any problems till now. I bought some blank Verbatim DVD+RW discs but found the recorder would not recognise them (ie, prepare disc for copy). I decided to buy my usual Phillips DVD+RW's again but now the recorder does not seem to recognise these either! It does however, recognise discs that have already got recordings on
