i have the cendyne [pioneer] 4x dvd-rw drive. im trying to burn a .IMG dvd image of something with DVD Decrypter. the buffer builds up fine, and then my compter locks up for about 6 secodns, then it seems to write a little bit, locks up for another 6 seconds,, writes a little bit.. and on and so on.. so more than half of the time its working the computer is absolutely frozen. anyone have any ideas?
