At the risk of here is another thing: the inclination to never change SHN .md5's and TTH roots can be used as justification to never fix SBE's or other problems. Someone gets a show, runs the len check and finds out there are SBE's. Then he fixes them before burning to CD, which consumes a little time and temporary disk space. A noob gets the same show, decodes, and burns a CD. There are pops between tracks, and he has just wasted a CD-R. You hard core never-convert people would at least agree that fixing SHN sets that have SBEs and convering to FLAC (since the TTH root is changed anyway) in a standard way should happen, right? The standard way of fixing SBEs could be: fix one set of .wav's at a time (for multiset shows), backward shift, pad last track with zero bytes.
