It is not easy to discuss the cdrecord-ProDVD topic in any language. Thus i prefer to stay quite neutral. Up to the last few days i thought that the issues around cdrecord and DVD were legal and interpersonal ones. Now i learned that there are a few other things involved. I will learn further, probably. > > I wonder wether Andy and Joerg are aware of a need for such > > extra treatment. (Listening for an echo now ...) > > ?? Ok. You both don't see any technical truth in the rumor spread by the person who tried to bite off Volker's head. Nobody else stood up.

My Cdrecord-ProDVD-Clone 2.01b31 does not know "full". It's about time i try the new 2.01.01b03 ... ... nope ... no blank=full ...

I -force blanked another media by cdrecord-ProDVD and could dvd+rw-format it to Restricted Overwrite afterwards. Nevertheless, growisofs aborted on OPC: :-[ PERFORM OPC failed with SK=3h/ASC=73h/ACQ=03h]: Input/output error I also tried the new growisofs option which avoids OPC. No success: :-[ [EMAIL PROTECTED] failed with SK=3h/ASC=0Ch/ACQ=00h]: Input/output error :-( write failed: Input/output error > I cannot recommend DVD+RW because the interchange compatibility > is too low.

You surely got more drives at hand than i, but within my own range of (mostly hearsay) experience there seems to be a tendency that +RW is more reliable. Possibly one should really start a multi-dimensional database in the web and record all the successful and not so successful combinations of drives and media. BTW: As my share of regression testing: Cdrecord-ProDVD-Clone 2.01.01b03 runs fine on SuSE 9.0, with my LG burner and 4x DVD+RW.
