Thank you Polytropon,
Byte order was really a problem.
Strange that burncd is supposed to take the original byteorder and
cdrecord takes reversed one.

burncd is still recommended by handbook for ATAPI CDROMs
for some reason.
I feel like cdrecord is much nicer and once suggested to retire
burncd in handbook and to always recommend cdrecord instead.
But some people disagreed.

Thanks for your helpful response,
