I'm pretty sure there is no transfer or remastering of the 5-8-77 Betty done by Charlie Miller. The circulating MSR>D copies all come from Dougal Donaldson's PCM (on VHS) copy made at the original (and only, so far!) transfer session. Bob Menke has an all-analog version on Beta HiFi but I don't think anyone has transferred that to digital. Rob Eaton then dbx-decoded a DAT transfer (from Dougal's PCM) using his studio equipment. Since the original is at 16/44.056, there is unlikely to be an advantage to using a higher digital resolution IMHO.
