I have recorded many TV programs with my Sony DVD recorder, model RDR-GXD455 (RDRGXD455). I hoped to have them for a long time. However, with this recorder a long time is about three weeks. That's about how long I can go with a DVD that is full of favorite TV shows before the Sony recorder erases the entire disk. When I check the menu to see what is on the DVD, the message says “There is no title” and there is nothing on the DVD. The player finalizes the disk too. There is no way to unfinalize the DVD either. At that point I have to reformat the DVD and start all over. I have lost about seventy programs on four DVDs so far, and the number keeps climbing. I am constantly loosing recorded DVD content to an unwanted DVD erasure. If I hadn't bought it so long ago, I would return it. I need to look for my receipt in case it has a one-year warranty on parts and labor. I can’t remember exactly when I bought it at Best Buy in Tempe, Arizona. I would look for another brand if you are buying a DVD recorder.
