It would help to verify the checksums on the target machine. Ideally under 
both Haiku and some other OS (Linux).

I don't know much about how CDs work. AFAIK a CD isn't accessible as a single 
linearly addressable data storage, but it has a TOC that describes individual 
tracks. Maybe the two programs write different TOC data and Haiku doesn't 
interpret them correctly in one case.

At any rate, if you can verify that another OS on the concerned laptop can 
read the CD correctly (i.e. the md5sum is correct), then please open a ticket.
