Sony RDR-GX300 DVD Recorder
After 19 months, will not play any disc.
I bought this unit in Oct. 2004. Until now I couldn't have been happier. Now, the unit will not play any disc - not the movies it recorded and not the store bought titles. However, I have had problems with the Sony blank CD-Rs I bought.  5 out of 25 were bad, and the unit messed up the recording.  The next blank set of 25 I purchesed were Phillips.  Only one out of 25 were bad. Now, I wonder if it was the unit instead of the discs.
