DVD-R Iincopatability?

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.

"For example, finalizing isn't always the same thing for all formats."

Except that the manual that was linked above clearly states on page 23 that discs recorded on the unit should be playable on regular DVD machines.

From the manual:

Finalize
Finalizing ‘fixes’ the recordings in place so that the disc can be played on a regular DVD player or computer equipped with a suitable DVD-ROM drive. Finalizing a Video mode disc creates a menu screen for navigating the disc. This is accessed by pressing DISC MENU/LIST or TITLE.

"Except that the manual that was linked above clearly states on page 23 that discs recorded on the unit should be playable on regular DVD machines."

I agree. But that's not what's happening. lol. Also, don't read too much into my last post. When you said you were baffled, and this should be straightforward, I was just listing some of the odd, fine points with regards to the formats were talking about.

I think I did come up with something that I'm pretty sure no one else has mentioned. Dual layer (DL) disc's. They're so common now that support for them on an older player could be easily overlooked.

Yeah. I've never used a dual layer disc so I'm not sure how they would act.
