I will cut to the heart of my problem by asking what is perhaps a silly question. My Pioneer DVR 103 generally writes CDs at 4x or 8x. Is there anyone to force it even SLOWER speeds(2x or 1x). My burner at this time neither reads nor writes any CD regardless of its brand, nationality or religious persuasion. Yet, it does read and write any type of DVD. The key differential here is the fact that the DVDs are all written at 1x speeds. So assuming dust and firmware are perhaps secondary considerations, you see what I would like to test. Thanks for any answers.
