Copying problems

[Learning to recorder]

I record 2 performances a day on DVD. The first recording copies no problems. The second recording which is usually a little longer will copy sometimes time. Other times it will not copy and I get no error information. I try copying on a Octavie Copy Master and a Bravo 4202. It fails to copy, but it will play on my computer

Poor media will fail near the outside edge -- the last part of the disc to be recorded. So use better media. There are only a few good manufacturers left. Try Verbatim Datalife Plus.

Be sure you're getting Verbatim Datalife Plus AZO discs. CMC Magnetics who now own the Verbatim brand has really upped the game of fool the customer into buying crappy second tier discs: https://forum.videohelp.com/threads/391272-Beware-of-new-Verbatim-non-AZO-packaging

The safest place to get them now is from Amazon: https://www.amazon.com/Verbatim-DVD-R-4-7GB-Recordable-Media/dp/B003ZDNZT2/ref=sr_1_11...880863&sr=8-11 DVD-R, https://www.amazon.com/Verbatim-4-7GB-Recordable-Media-Disc/dp/B003ZDNZSS/ref=sr_1_1?k...0880863&sr=8-1 DVD+R

Be sure to triple check the packaging when you get them. If there's no AZO logo, return them immediately. Unlikely that Amazon would purposely pull a switch, but it's easy to mistake the packaging.

It has happens with Verbatim and Philips Duplication Grade. I use DVD-R 16X 4.7GB all ordered through Amazon. I am not the one doing the recording but the person making the copies. Unfortunately different people do the recording. It hasn't happened consistently enough to say it is a person. They are recording on a Sony Recorder and I am thinking it is some step they are missing in finalizing but there was someone watching this week and said it was finalized.

Are you sure the Verbatim are AZO? As I pointed out in the link above, there are numerous types of Verbatim discs, but only the AZO are first tier. Philips has always been rebadged media as shown on this list: https://www.videohelp.com/dvdmedia?dvdmediasearch=phiips&dvdmediadvdridsearch=&type=12...+or+List+Media and is 99% sure to be second tier media today. Read here how to get the media code and check it on the DVD media page here.

Even if it turns out the user error that's causing the problem, the fact remains that the only first tier, known good media available today is Verbatim AZO and Taiyo Yuden, both now owned and manufactured by CMC Magnetics.

The fact that remains above all is that optical storage, especially DVD, is pretty much obsolete at this point, and is becoming more and more unreliable...
As for the original question, I fail to get a clear picture of what's going on (there seems to be something else than a DVD quality problem), mainly due to syntax issues (it reads as text which has been translated to Chinese and back to English, which is a bit problematic for someone seemingly living in the USA -- even the pseudonym has a grammar error ! o_O).
