Query: compatability

if it were possible i would not be unfavorably rating this specific product, but would be venting my dissatisfaction with the range of manufacturers who settled on the incompatable formats of dvd-rw and dvd+rw. call me naive, but i imagined that there was only one dvd rw and that plusses or minuses were simply a matter of the graphic designers preference.the idiocy that would give rise to this incompitability in functionality is surprising; to have it hinge on a + or - is baffling. it makes one wonder if it is somehow connected to a gatesian effort to thwart open standards.anyway, i suppose there will always be stupid people making stupid decisions. i'll throw myself in for buying on faith.scott
