Thanks BJKG for you information about SONY media and also thanks to chass0039 for any your suggestion.
Maybe i have found my problem, i still run some test but all my issue is for last firmware of my DVD burner (Samsung SH-W162C).
As suggested by chass0039 i buy 2 verbatim support:
- 1 DVD-RW Verbatim 4x compatible, SERL technology
- 1 DVD+RW verbatim 4x compatible, SERL technology
i downgrade SH-W162C firmware to TS009 and i successfully burn many DVD video playable on different DVD player (stand-alone,PC,portable)
i use my old media, but i create DVD video with some and different problem
i reformat with Nero my Sony media and use it and all works fine...
I definitly think that last firmware of my recorder have some problem in my configuration.
yes BJKG i use DVD-R for my DVD video backup, but i crate DVD-video from videorecording for wedding,sport and any other type of request.
I create a DVD video to distribute in order to view and validate my work, in this case i would like to use -/+RW media.
