Two pass mode? Please be more clear, what would you want two pass encoding for, especially in BSN? Nero doesn't do any kind of two-pass that I know of.
If you refer to something like: besweet -core( -input nix.ac3 -output c:\nix.mp4 -logfile BeSweet.log ) -azid( -c normal -L -3db -s surround --maximize ) -shibatch( --rate 44100 ) -bsn( -2ch ) That works without any problems (6.0.0.19 and 6.0.0.23). What other problem do you have with .23 libraries? tiki4
