You are correct for DVD-RW and with all DVD- formats, there are frequent round robin tests with all writers vs. allr readers and all media. This kind of test does not exist for DVD+RW and I've seen a lot of problems with media interchange. > I doubt BD-R will ever supplant DVD-R the same way DVD-R did with CD-R. > > When DVD-R came out there were no practical and affordable alternatives > for recording and transporting large quantities of data.

Just a note: When I got my first DVD writer in February 1998, the price of the writer was 15000 US$ and the price of a media was 80 US$. When I received my first BR writer, the price of the writer was 600 Euro and the price of a medium was ~ 20 Euro. Now the price for a medium is 1.5...3 Euro and the price for a writer is 60...200 Euro. It took 5 years for DVD to get into this price level and it took 5 years for BR to get into this price level. So where do you see a difference? There is another difference: the fact that flash memory has become cheap did change the interest of the people.
