many burning programs wil change yor aspi when u install it

unistall all burning software
update your aspi
unistal reinstall your burners

check device manager (before loading any burning software
are the drives recognised correctly???????

then install 1 bit of software,preferably prassi or recordnow (update pxengine),if u not got them use nero
check if drive works
add each writing software one at a time checking if writer still works

once i installed instantcd/dvd( old version i think it was this program) when installing it mentions aspi layers and it has its own,once installed my pioneer 103 as it was then wouldnt work
funny thing is the software was bundled with my drive
