i can rule this out, because although i used both a dvdr and cdr drive
for burning, both cds were read back in using the cdr drive.

any differences must have occured during burning. but since i used the
same toc file and disk-at-once mode, it's unlikely that the lead-in got
interpreted differently in both drives... but you are right, this being
a live cd, i used pre-gaps and non-silent gaps extensively - i'll
investigate some more along those lines.

best,

jörn
