primo/recordnow doesn't pick up!

[Shintaeh]

i can't seem to get primo/recordnow max to pick up my dvdr
windows/nero seems to pick up my pioneer dvr-105
but however primo and recordnow max doesn't, im trying to burn an "gi" file to disc.

:scanning buses -results in "no compatible recorder drives have been found in this computer"

-amd 1.4ghz
-80gig hd
-523 ram
-pioneer dvd-rw dvr-105 (master)
-pioneer dvd-rom dvd-114 (slave)

what can be the problem?
