Incidentally, Lame 3.91 disables VBR tags if --nogap is given. This is unnecessary, and should be commented out (in frontend/main.c) if you'll be using your gapless files on an Empeg.

Let me just clarify that! The current car-player software, even internal builds, always flushes the bit reservoir between tracks even for consecutive tracks from the same album. A future version will not flush the decoder in that case, which should allow true gapless playback, independent of whether a Xing VBR header is present.
