Rsjm80, Frankly I'm baffled. This really should be straightforward. Maybe in the early days of DVD recording you might expect to find some drives that supported either +R or -R but not both but we are far removed from the early days and I've not seen a drive in many years that didn't support both. Best of luck in any case. Dick"
Unfortunately, if you are using component style burners, you can run into all kinds of problems. For example, finalizing isn't always the same thing for all formats. DVD+ auto finalizes as it records. The problem is that even after you finalize a dvd-, there will still be differences because they don't finalize the same way. Then there's the matter of patents. DVD+, DVD-, RW, etc.. Are all held by different companies. Because of that, manufacturers sometimes try to steer consumers into formats and/or equipment they make money on. That's probably the issue here. If we had enough info to follow the money, this would probably all make sense. And if that's not bad enough, I remember that there were marketing issues where companies were naming features DVD+(some feature), or DVD-(some feature), and they were not actually referring to supported formats.
