What is the condition of each of these discs? EAC, in its proper ripping mode (secure, gap detection c, etc.) may take 8-12 hrs to rip a badly scratched disc, or one with a single but track-oriented gouge.
Edit: Or are you truly saying its hanging at the FLAC encoding? Dunno why that would be at all.....once it's in wav, whether temporarily or not, copy-protect issues and bad track issues are behind us. Hmmm.
