so generally it's a firmware <-> media brand problem and may be not that good firmware becuase it doesn't reload the supported speeds after a OPC failer. before a failer (& i think after i pass -speed=4) dvd+rw-mediainfo does displays 1x,2x,4x for DVD-R, after a failer it displays only current 1x & write #0 4x ( i never tried passing speed=1 or speed=2 after a failer and DVD recorded with speed=1 because of the failer to see whether growisofs changes to write speed #0 ) I'll try to find different(better) media to check it, but i doubt it will cause OPC failer. if it's firmware problem it shouldn't change to bigger speed even if the media is different kind right ? but if i do not find different media, i should use the speed setting to avoid OPC problems or to fix OPC problems, correct ? ( 1.) i never had OPC failers if speed is specified 2.) it's pretty hard to find 4x media where i live :( ) > > 2.)
