Burning problem

i just bought myself a pioneer ao7 8 spd burner…
it’s installed properly ( i think)… but…
whetever software i use… it only allows me to burn cd’s… no dvd burning option is available… i’ve updated the firmware…etc…etc
last dvd burner i bought ( the a04) required me to find and install some aspi drivers b4 it would burn… i’m not sure if this is the same with this burner… if so… or not… does anyone have a solution that would help??

currently using win xp home
intel 2.8gig

p.s. i’ve tried nero,gearworks and wincd ( all only allow cd burnhing… but recognise it as a DVD writer, the option to burn dvd’s is not highlighted or available)
