Is it possible to configure any DVD Recorder to automatically overwrite existing titles? I record a show each day with a recurring timer job, and I have to delete it afterwards each night to make room for the next day. I'd like the recorder to simply overwrite whatever's on the disc with a newer title (so I don't get the dreaded out of space error). I have a Sony RDR-GX300 and a Sharp DV-RW34OU. Thanks!
