ok, my computer had went out due to a power supply issue, i replaced the power supply and it worked perfect, well, it burned the movie no problems, well, i was going to do another movie, i inserted a blank dvd disc and it didn't read the disc, i inserted a movie, worked, i inserted a data disc, it worked, i inserted a scratched, program disc, it worked, i inserted a NEW blank DVD disc and it won't read it. i know it's not the drives (i have two and both do the same) because i put them in another computer and they work, the blank disc get read when the drives are on another computer, this is where i'm stuck, i wan't to be able to burn, any help would be great, oh i forgot, i'm using tdk dvd's and i used a verbatim dual layer and the same thing, but like i said they worked on the other computer, basically, imgburn says "medium not present" when i insert a blank disc, thanks to anyone that can help.
