DVD-R backups using copytodvd contain reading errors

when testing the backup on DVD-R (burned with copytodvd) some of them contain errors at 94 - 100 %, yet no error is reported in the log.
For testing the media after completion I’m using dvdinfo pro and alcohol

Please help. Anyone with similar problem?

do the dvd’s work?

Which writer and which kind of media did you use?

Princo 4X Pioneer 106 and they work fine on the player.

Ok, which version of CopyToDVD did you use to burn?
I suppose you wrote at 4x?

Yes, 4x and I also tried few Memorex 2x and TDK 2x.
The version(s) I tried where few, starting from the version after 2.2.6 all the way through the version just before 2.3.11.
The strange thing is when I use DVD-RW 2x there is no read errors towards 94 -100% (mostly at 100%.

Could you re-try with 2.3.12?

Okay, I will.
I’ll post the results.
Thank you kindly for your help.

Using dvdinfopro, selecting <test your media for read error> when it reaches 95% this is what it shows in the error window display and it just goes on and on… this is just partial copy and paste:
