As I didn't know exactly how to do blanking by hand, I
tried xcdroast - however, that program uses cdrecord
too so it doesn't solve anything - what's the program
to use for blanking ?

I'm not sure, but I think it was extremely low (only a

Sorry I don't know the exact numbers - my dad has the

I tried the following commend:
cdrecord -v -eject -dummy -force speed=2 dev=0,1,0
cd_image
The speed seemed to be 98%/100% the hole time - and
the minimum fifo fill was 81% - do you think this is a
reasonable number (say, enough to assume this will
work correctly) or should I try speed=1 ?
I was using the high value of speed=24 because that's
what the cd writer reports (48x24x48) - well any way
that's too much I see now.
