hmm. again, here's what i did:

i burned the same disk-at-once session four times, using the following
command:

cdrdao write /dev/<device> mytoc.toc

twice i wrote to /dev/cdrw, and twice to /dev/dvdrw.

all four disks were read back in using cdparanoia, to four different
directories: cdrw1, cdrw2, dvdr1, dvdr2.

when i cmp the files in cdrw[12], no diff.
when i cmp the files in dvdr[12], no diff.

when i cmp cdrwN to dvdrN, pooof! several thousand bytes differ.

wtf?????

please tell me it's really obvious and i'm doing something unspeakably
stupid.

regards,

jörn
