DVD-R/RW - Just the facts

[Kusanagi]

The RDVDC press conference presentation has found itself online (though, I swear I saw this before somewhere...). An interesting read and really puts things into perspective from Pioneer's side - which we haven't seen too much of recently.

Info and the d/l link to the presentation is available at this thread here - http://www.dv-info.net/cgi-bin/ib/ikonboard.cgi?s=3d234dd52d7dffff;act=ST;f=3;t=114

After reading that, why is Mt. Rainer being hyped up so much (mostly by KennyShin here) as the next best thing, if media written in the Mt. Rainer format will not be compatible at all with current DVD players or available DVD-ROMS? Guess I'll stay away from that for awhile...then again, I can't recall a time I ever trusted packet-writing for making data/backup cds...

I agree with you that present day packet writing S/W sucks. In fact, I don't load it on my system because it is a resource pig. But, Pioneer is saying there is no advantage with MRW. The big advantage is that the defect management is done at the drive level which keeps the Host out of the way. Will MRW disks be readable in non MRW DVD-ROM drives? Yes! You will have to install a reader(basically a lower level UDF driver). Will it be readable in DVD players? No. Am I going to use DVDMRW to author DVD Video Disks? No. Is the typical user? I doubt it. It will be faster to author a disk with say Nero or Roxio then trying to Drag and drop a DVD video onto a disk. On top of that you eat up precious disk space with defect management sectors. Thats with MRW or the present S/W that is available today. With Pioneer's method you will still have to keep the Host involved in the Defect management(resource pig). With -RW you cannot do defect management at the 2K block level. It has to be on a 32K boundary(resource pig). Even MS indicates that this is a problem.
Remember that MRW is for data backup and hopefully floppy replacement
not Video authoring.

How can a drive that requires special software to be installed replace floppy disks?

Just put in a floppy disk and it works fine.
