Replying to my own message, it appears I was premature in my optimism .. 4.3 does still suffer this problem, just for some reaosn it seems different discs may affected. As a solution ... is there any qualty related problem, given the inherent SP-->256K conversion on importing, to make a two step import ... SP-->PCM/WAV followed by PCM/WAV-->256K? My instincts tell me the software likely does something like this behind the scenses anyways.
