I have a Sony RDR-HXD890 DVD Recorder but am finding it difficult to play DVD's recorded on my PC. When I load a DVD the recorder says NO TITLE but will not let me add one. I am trying to play a DVD downloaded from You Tube which I converted to DivX format. What am I doing wrong? I am using a Memorex DVD+R 16x 4.7GB. Would appreciate some ideas to try.
