I've got a few hundred megs of Ogg Vorbis files I've collected over the years that I want to convert to MP3 so I can put them on my iPhone (among other things.)
Converting from one file format to the other isn't all that hard (see, for example, this other SU question.)
But - the ogg files I've got have fully loaded metadata headers that I really want to be carried into the ID3 tags of the resulting MP3 file. So far, I havn't been able to find a program that will batch convert OGG to MP3 AND port over all metadata.
(I'd also like something Free/Open Source and windows based, if possible.)
