Found a bug in metamp3 (bug post here) which explains your problem.
Here's the fix to both .cfg files:
REACT-track.cfg:
IF %add_rg%==1 @tools@\metamp3.exe %RG_MetaMP3% *.mp3
change that line to:
IF %add_rg%==1 @tools@\Glob.exe -v -c @tools@\metamp3.exe %RG_MetaMP3% *.mp3
REACT-image.cfg:
IF %add_rg%==1 @tools@\metamp3.exe %RG_MetaMP3% *.mp3
IF @ApplyAlbumGain@==1 @tools@\metamp3.exe %ApplyAG_MetaMP3% *.mp3
change these lines to:
IF %add_rg%==1 @tools@\Glob.exe -v -c @tools@\metamp3.exe %RG_MetaMP3% *.mp3
IF @ApplyAlbumGain@==1 @tools@\Glob.exe -v -c @tools@\metamp3.exe %ApplyAG_MetaMP3% *.mp3
NOTE!
There's also a limitation in EAC (post #225) which crops long titles in cue files to 80 chars (first 77 chars of the title + 3 period chars). What this means in REACT is that when ripping tracks in image mode (F10), the track filenames are taken from TITLE fields by ACDIR and if the TITLE is cropped in the cuesheet, then you get cropped filenames PLUS cropped track title TAGS!! This affects ALL encoded tracks in image mode. In track mode ripping there's no problems.
gsa999, remember that if you copy RG values to files which haven't been in the calculation process with the other files, RG values are not correct for that whole album.
