The lame project's CVS data is in read-only mode, so the project may have switched over to another source-code-management system. To check, visit the Project Summary Page for lame and see if the menubar lists a newer code repository, such as SVN or Git.
The CVS data can be accessed as follows.
You can run a per-module CVS checkout via pserver protocol:
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P hip
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P lame
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P logo
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P newweb
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P py-lame
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P vc_solution
cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/lame co -P webpages
You can view a list of files or copy all the CVS repository data via rsync (the 1st command lists the files, the 2nd copies):
rsync -a a.cvs.sourceforge.net::cvsroot/lame/
rsync -ai a.cvs.sourceforge.net::cvsroot/lame/ /my/local/dest/dir/
