As I've said to many repeatedly, there is a massive difference between a media that is a "pie-slice" sectored, like MO, and a media that is "single-groove", like pressed and WORM. If you record a MO in "emulated" WORM, then end-device player _must_ know how to "emulate" it as a "single-groove." That's why many CD-ROM drives could read CD-R, but not CD-RW. Because CD-R WORM is still physically tracked like CD-ROM, but CD-RW MO is not. Same deal with DVD players and DVD-R WORM versus DVD-RW and DVD+RW MO, and the DVD+R "hybrid". CD-R and DVD-R are "single-groove" WORM. CD-RW, DVD-RW, DVD+RW are "pie-slice" MO. DVD+R is some hybrid MO, because Sony/Philips +RW drives couldn't do a WORM "burn" (not until the dual-format Sony 500 series came out -- but then DVD+R had already been established). Matsushita/Panasonic PD-CD and DVD-RAM are improved reliability MO, adopting a lot of former costly and proprietary approaches, into an official standard for optical archiving. It's not for consumer use (although some high-end consumer video devices used it because it came out 4 years before DVD-RW and DVD+RW), hence why it isn't advertised much, but it is very much in volume, and will be for a long time. -- Bryan J.

Unfortunately, too many Linux advocates port over the so-called "choice" from the commercial software world, brand name marketing. The result is false assumptions, failure to focus on the real technical similarities, but loyalty to blind vendor alignments. _______________________________________________ Dvdrtools-users mailing list Dvdrtools-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/dvdrtools-users
