    I tried to follow the same procedure that works for DVD+RW

    Select ISO file

    Yes

    But for some reasons it won't burn on DVD+R, just starts to
    destroy the disc (not empty on a new test)

    Attach the last.log from K3b (missing privilegies?)


I googled this error with cdrecord and then there was google groups forum with recommendation on upgrading cdrecord

ATAPI DVD burner:
As an update, I have now tested K3b burning on my second workstation (Supermicro) with a DVD burner type ATAPI, also scsi. Got success with all three disc types, DVD+RW, DVD+R and DVD-R burning the iso image the same way.
The Samsung UBD Blu-ray player doesn't accept the DVD+/-R discs either.
For now I just attach the log files from burning the DVD+/-R, and can add media output if of any interest.


Update 5/12:

BD-RE 2x 50GB disc (TDK)
BD-R 6x 25GB disc (Verbatim)

K3b with the Blu-ray burner wrote the iso file OK to both discs without failure.
OK playback video and audio with VLC from BD-R/RE discs without stuttering.

Samsung UBD Bluray player accepted the discs and started auto playback
The video image was quite distorted (green/grey/white mosaic flickering)
Tried to change player's Auto image setting, resolution etc without solving.

Will try to change ffmpegs encoding profile and/or color depth next.
At least the PCM audio could be hearing and played OK from BD-R/RE discs :)
