This is an issue that I haven’t quite grasped as I’ve been looking for media for my old Pioneer 106D. Its not a major problem as I’m sure I’ll be upgrading in a few months, but its just something I’d like to understand better. What I’m wondering is if firmware needs to contain actual data on a certain media code in terms of writing strategy in order to produce a good burn, or whether having this data improves the quality of a burn.
My sense is that this must be the case, otherwise you wouldn’t see older 4x drives producing higher error rates with quality 8x media than with average-quality 4x media. I’m still curious, to what extent is this a problem? Should I be choosing media like CMCMAG.AF1 over TYG02?
