I wonder if anybody can help me....this may be a simple question with a simple answer..... I have recently purchased a Sony RDR-GX210 DVD Recorder, and the media I have purchased with it (4x speed) is no good. The Sony hand book is saying that it will only support 2.4x media. I have heard that you can get firmware upgrades for the DVD Recorder to enable it to use the 4x media, however cannot seem to find it on the web.... Any idea's? Other than going out and buying 2.4x media?
