I recently purchased a Toshiba DR 570 DVD recorder and have been happy with it. The only thing is that the discs I burn in the recorder cannot be seen by the DVD drives on my computer. It isn't a firmware issue as I have updated that. In fact I've tried the discs with two different brands of media (Sony DVD-R and Philips DVD-R) on several different computers-including some Toshiba laptops-all to no avail. I've also tried it with discs that were finalised and open. Does anyone have any suggestions as to why I'm encountering this problem and how I can avoid it in the future? Do you think it's media related or what? Many thanks for your help.
