You are, once again, mistaken on Jorg's CDRecord-ProDVD. You have to use a block access approach for DVD+R. Jorg has added this in 2.01a11+, but for _only_ for Ricoh firmware. I don't think Sony/Philips designs are supported (yet?). I'd be interested to find out what Ricoh is doing differently (translation of Matsushita/Pioneer to Sony/Philips commands?). Previously, Jorg only added DVD+RW drive firmware support to record DVD- R (and DVD-RW in "record" emulation), and not DVD+R (or DVD+RW for that matter) itself. That's because, as I've detailed many times, DVD+R is not like DVD-R. Jorg's release notes talk about that. Also know that DVD-RW is physically different than DVD-R as well. Although you can "emulated" a recording to a DVD-RW (just like CD-RW), it is _not_ recommended, and a real DVD-R (just like CD-R) should be used. DVD+R is already half-way there -- as Jorg says ... "A DVD+R is written in a mode something between TAO and packet writing mode." There are similar limitations/issues to any device that can only be written in block mode. DVD-R can be written in either, just like CD-R. > Eg growisofs -Z /dev/dvdrecorder=dvd.iso must > work, if it doesn't, "get DVD-R" is at best a workaround if the bug > can't be fixed, but not an answer. > Did you try with a 4.7G DVD+R(W), to eliminate the dual-layer factor? Also remember that 4.7GB (GB=10^9) is only 4.35GiB (GiB=2^30). Most OS utilities report GB using base 2, not base 10, so they are really reporting GiB. The "Xi" (metric-binary) were only recently standardized by the IEEE and, I believe now, ISO. Newer OS software/utilities are starting to use the nomenclature as the base 2 and base 10 prefixes vary by a great amount. E.g., 1TiB = 1.1TB -- ~10% difference, quite significant, and it's only getting greater with greater numbers. -- Bryan J.
