you probably have SBEs on all of your shows then... try running a "len" check on one of your shows this way, it will tell you if there are SBEs or not. (TLH analyze tab)

never does any harm to check the 'align on sector boundaries' box, enable that for sure

SBEs aren't a problem for a computer, but if the show is burned to audio cdr you will get microgaps except nero which will delete out some of the samples (!!)
