Sony DW-D22A won't burn DVD-R, DVD+R DL



My DW-D22A won’t burn CMC MAG. AE1 DVD-R discs, Nero gets to “Checking Discs…” and then freezes, can’t close it, can’t cancel it, can’t kill it, can’t reboot, can’t shutdown system, have to cut power. Same thing happens when I try to burn DVD+R DL except at “Writing disc…” lead in. Anyone know what I can do? Same thing happens using BYS3, and BS0S. Right now I’m using the original BYS2
