After deleting unwanted material with vobblanker, is running ifoedit (especially using its
"get vts sectors" button) equivalent to running fixvts or is one of these preferred over the other (if so, why?)?

Sometimes ripit4me will say something to the effect: Possible scratch/dirt, cell was not
in protected cell list...". Yet, I monitored the dvd decrypter window and it always showed the number of read errors to be zero. How could ripit4me think one or more cells, sectors, or whatever might not have read in right if dvd decrypter never indicated there were any read errors???
