As you got a medium error it probably makes sense to try a disc
from a different manufacturer. Check the output of
cdrecord dev=1,0,0 -atip

I'd be surprised if switching from cdrecord to burncd would
solve the problem.

While it has nothing to do with your medium problem,
you should enable DMA on acd0.
