problem writing business-card cdr

hi there,

i just found bbc linux and wanted to write it on a business-card cd. but
cdrecord refuses me to do so for some reason.

the cdrw writes all other media very nice, for some reason it simply has
problems with small cdr-media.
i get the same problems when trying to write one of those mini-cds.

is there a special trick to write those things with cdrecord?

thanks in advance,
toskala

the cd writer:

copy and paste what i do, and what i get:
