ok, have proof now. download Paulway's Club Mix 2003, which is VBR encoded. in winamp, and tag&rename, it displays the time as 115:58. when imported using (j)emplode, it reads 116:14.
Good catch. It looks like all current versions of Emplode and RMM believe Xing-header VBR files to be 0.227% too long, due to a rounding error. FITNR.
