Hi: OK, capital M is 48khz, cd quality is 44.1khz. Depending on your soundcard, you may not be able to use 48khz. Most probably, any 48khz files you can infact use will probably be downsampled to 44.1khz upon playback, unless you've got a funky soundcard. Lame by default encodes at 128kbps stereo. If you use the -a switch to downmix to mono, the default is 64kbps. Finally, you don't need to do a distupgrade necessarily to use a package from unstable. In theory, it should let you know if other packages need to be upgraded in order for it to work. Having said that, however, compiling from source is pretty straight-forward, and you might be able to grab binaries for stuff anyway. What do you want to do with vorbis anyway? There are binaries for oggenc (an encoder) and freeamp 2.1beta6 is apparently out now (according to one of the developers who wrote to me personally to tell me) and that should do for playing them.
