As requested my useful freeware recommendations as they spring to mind from help offered.
Free DVD MP3 Ripper: Does what it says on the tin.
And a bit more besides. Converts DVD (*.vob), VCD/SVCD movie files(*.dat) and MPEG( MPEG-1, MPEG-2) files(*.mpeg, *.mpg) flawlessly to MP3 at user determined bitrates & sampling. Also edits ID3 tags.
