DVD-R Iincopatability?

OK, I have to look, I have been real busy today with a car show, I'll get back to you on that but I found in the specs for one of the new LG units that IT DOES say that the format is different, it may not say that in my manual but I'll check again and let you know.

Rsjm80, After browsing through the manual (thanks for the link Jea48), I don't see any reason why the disc you recorded and finalized shouldn't be a "standard" DVD playable in other machines. The manual even states that at one point. Also, it doesn't appear that the non-standard recording length I mentioned above is even an option on your machine.

One thing I thought of while reading through the manual - if the program you recorded is that valuable to you, you can always use your machine to dub it to VHS. I know this is not optimal because of the loss of some quality but at least you would have the program. I'm also sure that you can find a service to create a DVD from the tape.

Jea48 & Djohnson54, I have searched the manual and cannot find that it states there could be format differences. I did find that in the newer LG recorders though. I even thought that maybe the recording mode was wrong but, the manual says that DVD-R discs always default to Video mode and as such they (in theory) should play in others. That's why it baffles me as to why it won't play on my friend's earlier Sanyo or the newer RCA surround unit. I thought that maybe the format selection might be wrong and be in VR mode but, since the DVD-Rs default I can't be wrong so it only comes down to a format difference then as now stated in the newer models.

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.
