I am not sure which media to buy. Also, when I do choose one, what kind should I get, or does it even matter? I see that there are silver/purple discs, high quality silver/purple discs, and white discs. They all cost around the same, but what's the difference? I have asked this question before, but none of the sites I go to say "compatible with Pioneer 106..." they all stop at the 105. I just want to make sure they'll work. Thanks!
