Is there any significant difference between DVD-R and DVD+R? Do new DVD burners recognize all DVD formats? My DVD player playes DVD+R, but not DVD-R. Also, a stand-alone DVD burner could not read or burn CD-Rs. Who are these DVDforum(DVD-R) & DVDalliance(DVD+R), and why do they support 2 different formats when no one cares and blue ray and HD are out? Why are there no CD+Rs? Whats the deal with speeds? I see all are 16x now. A spindle of 100 DVD+Rs 4X is selling in NYC for $19.99; but 16X for $24.99. Interestingly, my CD-R burner cannot burn CD-Rmusic, but the DVD burner can.
