I'm now at home at a different burner but I probably don't have a 
different CD recording software other than cdrecord
available. that's Windows XP BTW, under which I burnt that CDs. I could 
prbably boot an older (4.x) FreeBSD
on that machine but that would be CD record, too. Medium is also a 80 
min 700 MB CD. Weren't they  650 MB in earlier times actually?
Earlier times I mean, when I still had my FreeBSD subscription and got 
each release in a neat CD set :-)

Oh well, I will give it another try and see how it works out.
